Does investing in double and triple glazing increase property value?

Double and triple-glazed products are well established as a way to increase property value by improving thermal efficiency, reducing energy bills, and increasing security. New products come with guarantees covering unlikely repairs. They also increase the desirability of a property when it comes to sale.

How much will upgrading my property with new glazing cost?

Cost depends on the number of products, materials selected, and scope of works. uPVC is typically less expensive than aluminium; both offer similar thermal and security benefits, though aluminium is stronger and lasts longer and suits more contemporary, minimalist designs. Upgrading double or triple glazing improves energy efficiency and increases property value, particularly when all products are replaced at once. Accurate costs are provided at the free quote stage.

How do I know when my windows and doors need replacing?

Double glazing typically lasts 20 to 35 years with proper maintenance. Condensation between panes, draughts, leaks, or water pooling around frames are signs that replacement is due. Damage to seals and structural damage almost always requires full replacement rather than repair.

Should I replace all my windows at the same time?

Replacing a full set of windows at once maximises energy efficiency gains and can increase property value by up to 10%. It also improves the property's appeal to buyers at point of sale.

Does improving my home with double glazing need planning permission?

Double and triple glazing typically falls under permitted development and does not require planning permission. Exceptions apply for listed buildings, which require like-for-like replacements, and for properties in conservation areas. Seal-Lite can advise on planning requirements during the free quote process.

Which council represents Weston-super-Mare for planning purposes?

Weston-super-Mare is primarily represented by North Somerset Council, a unitary authority responsible for all major government services including planning. North Somerset Council handles all planning applications. Weston-super-Mare Town Council operates at parish level, managing smaller community assets. All planning applications for window and door work must be submitted to North Somerset Council.

Where exactly is the Great Weston Conservation Area and how do I check if I'm in it?

Created in 2018, the Great Weston Conservation Area is divided into four distinct character zones. The Seafront covers Birnbeck Pier in the north to the Royal Sands at the south end of the beach, with key streets including Birnbeck Road, Knightstone Road, Marine Parade, and Royal Crescent. The Hillside covers the slopes of Worlebury Hill above the town centre, with key streets including South Road, Cecil Road, Atlantic Road, and The Shrubberies. The Town Centre is centred around the main shopping streets and Civic Quarter, with key streets including The High Street, The Boulevard, and Orchard Meadows. Whitecross is south of the town centre towards Uphill, with key streets including Ellenborough Park (North and South), Walliscote Road, and Uphill Road North. To check whether a property falls within the conservation area or an Article 4 direction zone, use the North Somerset Interactive Planning Map at map.n-somerset.gov.uk and toggle the Conservation Area and Article 4 layers. Conservation area boundaries can expand, so it is always advisable to verify with the council.

What were the Heritage Action Zone programmes in Weston-super-Mare?

Parts of Weston-super-Mare's town centre were covered by two Heritage Action Zone programmes: the Great Weston Heritage Action Zone (2017–2022) and the High Street Heritage Action Zone (2020–2024). Both programmes aimed to restore original shopfronts and windows to traditional materials, with a combined investment of £2 million. The council used incentives to replace materials including uPVC with traditional timber alternatives within the zones. Both programmes have now ended — the Great Weston HAZ concluded in September 2022 and the High Street HAZ in March 2024.

Which buildings in Weston-super-Mare are listed?

Weston-super-Mare has many listed buildings, and properties near them are typically expected to respect the period style and character of those landmarks. Key examples include Royal Crescent (Grade II listed, built 1847 by James Wilson of Bath), Ellenborough Crescent (Grade II listed Victorian terrace where standard double glazing is typically refused), Knightstone Island bathhouses and theatre buildings (individually listed), large villas on Atlantic Road and South Road (many individually listed), Birnbeck Pier (Grade II*), and the Town Hall (Grade II listed). Any works to listed buildings or properties within their setting require listed building consent and are subject to strict requirements.

Windows, Doors & Conservatories in Weston-super-Mare

Q: When is it time to replace my windows or doors?

Clear signs that replacement is needed include draughts indicating seal damage, visible wear or discolouration, locking mechanisms that stick or fail to close properly, and products that are 10 to 15 years old or more. At this age, thermal efficiency will have declined noticeably compared to new installations.

Q: What are the benefits of double glazing?

Double glazing improves energy efficiency and reduces heating bills, enhances security, reduces external noise, controls condensation and moisture, and increases property value and market appeal.

Q: What planning considerations apply when obtaining permission from North Somerset Council?

Most window and door replacements fall under permitted development in North Somerset. However, Article 4 directions and conservation area protections apply across several parts of the district and can affect window replacements and material changes. Restrictions in Weston-super-Mare are stricter than in many other parts of North Somerset due to the town's Victorian seaside character and the creation of the Great Weston Conservation Area in 2018, which consolidated five previous conservation areas into one large area with four distinct character zones. Affected zones include The Seafront (Marine Parade, Knightstone, Birnbeck Road), The Hillside (South Road, Cecil Road, Atlantic Road, The Shrubberies), The Town Centre (High Street, Orchard Meadows, The Boulevard), and Whitecross (Ellenborough Park, Walliscote Road, Uphill Road North).

User-friendly and first-class security features, the uPVC doors we install throughout Weston-super-Mare will help you to retain heat and conserve energy, reducing your heating bills.

Replacement Windows To Make Your Home More Efficient

From contemporary to more traditional styles, we offer double and triple-glazed replacement windows for homes across Weston-super-Mare.

Whether your current windows are old or damaged, or you’re just wanting to improve the look of your home, we can help you choose the right windows to fit seamlessly into the architecture of your home, whether that’s keeping in line with the charm and historical feeling of a period home, or complementing an already contemporary and stylish residence.

Opting for new windows is an excellent step to take in making your home more energy efficient. After all, the coastal weather is harsh and unpredictable, so the additional measures to make your home warmer, quieter and more secure are all worth it.

All of our windows are designed with energy efficiency in mind, as we only offer ‘A’ and ‘B’ energy-rated glazing, with low U-values of just 0.8 with our triple-glazed units. We can also offer an extensive range of window hardware, including monkey tail, teardrop and connoisseur offset window handles, to allow you to make the windows your own.

Energy Efficient Composite Doors in Weston-super-Mare

Composite doors are also built with energy efficiency in mind. With a variety of finishes available, including classic woodgrain effect, bold statement colours and on-trend shades, you’ll be sure to find a composite door that fits your Weston-Super-Mare property. Perfect for both contemporary and traditional homes, and with a great level of customisation, you’ll be able to create the perfect door that has real ‘wow-factor’. As your front door is the first thing that people see when approaching your property, investing in a composite door is known to increase the overall kerb appeal and value of your property.

We understand that homeowners are likely concerned about their home’s security, so all of our composite doors are constructed with state-of-the-art security systems as standard. It’s important to note that composite doors are some of the strongest doors on the market, simply because composite is thicker than uPVC and contains a combination of uPVC and other materials.

Exceptional Bifold Doors and Patio Doors

Bifold doors and patio doors are highly popular as they create a stylish connection between the indoor and outdoor spaces of your home. Allowing natural light to flood your home, whilst enhancing and emphasising the beauty of your outdoor space.

Both are becoming highly popular choices for outdoor doors, yet they both provide different benefits. The choice that you will make largely depends on the style of your home and your personal preferences.

Bifold doors allow you to open up an entire wall or create a single or double entrance door for easy access. A patio door will offer large expanses of glass with various configurations for opening and closing. Sliding patio doors are highly popular due to their sliding nature, which allows the doors to tuck into themselves, maximising space available once the doors are opened.

Grow Your Usable Living Space With A Conservatory in Weston-super-Mare

Gone are the days when a conservatory would be ‘that’ space where it’s cold in the winter and unbearably hot in the summer. Old conservatories gained a bad reputation because they were constructed with cheaper materials and complied with building regulations at the time, but that was not thermally efficient.

Modern conservatories are highly efficient and can become fully functional living spaces all year round, increasing the amount of space available on your property. Built with highly thermally efficient materials of the highest quality, a modern conservatory can be used for a variety of different uses, from a home office to a dining room or even an extension to your kitchen area.

Our team will support you to choose the perfect conservatory to suit your existing home, design style, budget, and individual needs.

We can supply Lean-to, Victorian, Georgian, Gable-end, T-shaped, P-shaped and HUP conservatories in Weston-Super-Mare, as well as more bespoke options.

Frequently Asked Questions

Does Investing In Double And Triple Glazing Products Increase Property Value?

Double-glazed and triple-glazed are known to increase overall property value when they are installed on your property. This is because they increase the overall thermal efficiency of your property which saves money on energy bills as well as increases the overall security of the property. New products have guarantees which ensure that any unlikely repairs that are needed are covered when your new products are installed. Double-glazed and triple-glazed products also increase the desirability of your property when it’s time to sell for the reasons mentioned above.

How Much Will Upgrading My Property Cost?

When upgrading your property with double or triple-glazing, the cost of the project will depend on the number of windows, doors and other products you choose, as well as the materials. All of our products are manufactured with the highest-quality materials, with UPVC, Aluminium and Composite products being available. UPVC is typically cheaper than aluminium, and they have similar benefits. UPVC have a more classic look, whereas aluminium is a great choice for more modern, minimalist designs. Aluminium is stronger and typically lasts longer than UPVC, but it will increase the cost of your project. When you invest in double or triple-glazed products, you will make your property more efficient. This slashes your energy bills, making a return on your investment. They also increase your overall property value, especially when upgrading everything at once. We will advise you on accurate costs when looking to upgrade your property.

When Is It Time To Replace My Windows or Doors?

There will be several clear signs that it’s time to replace your windows and doors with the main sign being that they cause draughts and aren’t keeping the cold out and the heat in. This is usually due to damage to the seals over time which means that they likely will need to be replaced. Other signs include:

You can physically see that they are worse for wear – usually when they are over 10 to 15 years old.
They do not operate properly and the locking systems are sticking or not shutting correctly.
There is visible discolouration to the windows or doors.
They are very old from 10 to 15 years old. This will mean that they won’t be as thermally efficient as new installations.

How Do I Know When To Replace Windows And Doors In My Property?

Double glazing typically lasts from 20 to 35 years. UPVC and aluminium last for this long when fairly maintained. If you have problems with condensation, drafts, leaks, or you have water pooling around the window or door, then it’s probably time for an upgrade. In some cases, you can repair the damage, but damage to the seals and structural damage almost always will result in the need for replacement.

Should I Replace All Of My Windows At The Same Time?

If you are replacing your windows, it’s a great idea to consider replacing an entire set of windows. This can massively increase the efficiency of your home and slash energy bills. You can expect to increase the overall value of your property by up to 10% when upgrading a set of windows. This massively increases the appeal of your property, which makes it more attractive when it’s time to sell.

What Are The Benefits Of Double Glazing?

Double glazing has a range of benefits. It increases the overall value of your property as it makes your property look new and slashes energy bills. Energy efficiency is one of the biggest benefits and is very important to homeowners. Double glazing also reduces noise from the outside. Double glazing also reduces moisture and controls condensation, which makes your property healthier and keeps the glass clear all year round.

Does Improving My Home Or Property Need Planning Permission?

Upgrading your home or property with double or triple-glazing products typically falls under permitted development, so it doesn’t require planning permission. You will still need to contact your local council or planning authority to ensure that works are in compliance. If you have a listed building or the property is within a conservation area, then you will likely require planning permission. Listed buildings are more difficult, as you will have to install a like-for-like replacement. We can advise you on planning permission if you have any questions about this during your free quote.

Which Council Represents Weston-Super-Mare?

Weston-Super-Mare is primarily represented by North Somerset Council, the headquarters of which is in the town. This is a unitary authority which is responsible for all major government services such as education, housing, council tax and waste management. Weston-Super-Mare Town Council operate at the local parish level, managing smaller assets in the community such as parks, graveyards and public toilets. North Somerset Council handle all planning and planning applications, so this is who you will need to apply to if you need to obtain planning permission.

Information and Considerations When Obtaining Planning Permission From North Somerset Council

As the area that is covered by North Somerset is smaller than Bristol City Council’s (BCC), the application process should be faster, as BCC have to process more applications each year. They are still busy, though, so this is an important factor to consider should you need to obtain planning permission. For our products, you typically will not need planning permission, as you will be exempt under permitted development. However, the council has certain rules where you will likely need planning permission.

Article 4 directions and conservation area protections apply across several parts of North Somerset, and they often affect window replacements and material changes. The council enforces this for properties within many designated boundaries. In Weston-super-Mare, restrictions are stricter than in other areas in the district. This is largely due to the town’s Victorian seaside identity and the creation of the Great Weston Conservation Area in 2018, which consolidated five previous conservation areas (Birnbeck, Melrose/Grove Park, Boulevard and Montpelier, Beach Lawns, and Ellenborough Park) into one large area with four distinct character zones. Particular areas include The Seafront: Marine Parade, Knightstone, and Birnbeck Road. The Hillside: South Road, Cecil Road, Atlantic Road, and the Shrubberies (Known for its high-value Victorian villas). The Town Centre: The High Street, Orchard Meadows, and The Boulevard. Whitecross: Ellenborough Park, Walliscote, and Uphill Road North.

Where is the Great Weston Conservation Area?

Created in 2018, the area is divided into four distinct “Character Areas”.

The Seafront: Birnbeck Pier in the north, all the way down to the Royal Sands at the south end of the beach.

Key Streets: Birnbeck Road, Knightstone Road, Marine Parade, and Royal Crescent.

The Hillside: Covers the slopes of Worlebury Hill, sitting just above the town centre.

Key Streets: South Road, Cecil Road, Atlantic Road, and The Shrubberies.

The Town Centre: Centred around the main shopping streets and the “Civic Quarter.” The High Street Heritage Action Zone (HAZ) programme overlapped with this area until it ended in March 2024.

Key Streets: The High Street, The Boulevard, and Orchard Meadows.

Whitecross: South of the town centre, heading towards Uphill.

Key Streets: Ellenborough Park (North and South), Walliscote Road, and Uphill Road North.

What’s the Best Way to Check If I’m in the Great Weston Conservation Area?

If you are unsure, it’s always recommended to check with the Council. Conservation areas can expand, so the information that you have been given when you purchased the property may have changed. You can also check out the North Somerset Interactive Planning Map and toggle the “Conservation Area” and “Article 4” layers. This provides a detailed map of the entirety of North Somerset and will show if you are within the zone.

What’s the Best Way to Check If I’m in the Great Weston Conservation Area?

What Was a Heritage Action Zone? (HAZ)

Parts of Weston’s town centre were covered by two Heritage Action Zone (HAZ) programmes, the Great Weston Heritage Action Zone (2017–2022) and the High Street Heritage Action Zone (2020–2024). The goal of this was to restore the original shopfronts and windows to ‘traditional’ materials with a combined £2m investment. The Council used incentives to replace certain materials, including UPVC, in properties within this area with traditional timber alternatives. Both programmes have now ended: the Great Weston HAZ in September 2022, and the High Street HAZ in March 2024.

Listed Buildings in Weston-Super-Mare

Weston-super-Mare has many buildings protected by listed status. Properties around listed buildings typically need to respect the period style and character of those landmarks. Classic examples include:

Royal Crescent: One of Weston’s most iconic Victorian landmarks (Grade II listed, built 1847 by James Wilson of Bath).
Ellenborough Crescent: A highly protected Grade II listed Victorian terrace where standard double glazing is typically refused.
Knightstone Island: The old bathhouses and theatre buildings, several of which are individually listed.
Atlantic Road / South Road: Many of the large individual villas are listed.
The Grand Pier & Birnbeck Pier: Both leisure attractions, but their listed status (Birnbeck is Grade II*) and prominent positions affect planning decisions for surrounding properties.
Town Hall & Magistrates’ Court: High-status civic buildings (the Town Hall is Grade II listed).
