Weatherseal Windows Review [Dissolved]: Top 3 Alternatives
Overall, out of 10
- Price
- Not scored: Not sourced. The company stopped trading, so there are no current quotes, and our cost pages have no Weatherseal quote data. The page body's £160–£2,700 per-window figures are generic window prices, not Weatherseal quotes, and they have no header evidence.
- Not scored
- Guarantee
- Not scored: Not sourced. The company's own website is gone: weatherseal.co.uk now hosts unrelated adult content, fetched 2026-09-24. No official or company page stating a guarantee length could be fetched. Trustpilot reviewers mention a '10 year guarantee', but that is hearsay and is not used.
- Not scored
- Accreditation
- Not scored: Not sourced. FENSA's installer search renders client-side and returned no results when fetched. No TrustMark or Certass listing was found. The company is dissolved, so it cannot hold a current registration, but no register page confirms this, so no score is given.
- Not scored
- Customer rating
- Not scored: Not scorable. The Trustpilot profile for weatherseal.co.uk ('Weatherseal Home Improvements') is closed to new reviews because the website has closed. It lists 472 reviews, with 0 in the last 12 months (the latest is dated 15 Feb 2022), and it shows no TrustScore. The rubric needs a score on the day, so this is null. The 4.1 in the packet belongs to Weatherseal Windows Ltd, Leicester (weathersealwindowsltd.co.uk), which is a different company.
- Not scored
- Companies house
- WSHI Realisations Limited, formerly Weatherseal Home Improvements, no longer trades — the company entered insolvency and the brand's consumer operation is gone (Companies House). find-and-update.company-information.service.gov.uk

Weatherseal Update
Are you looking for reliable installers to install new windows or update to double-glazed ones?
You may have considered Weatherseal, which was among the top four largest glazing installers in the UK. However, the company started having financial troubles in 2017, owing creditors over £12 million, and went under administration. By 2018, the company was dissolved.
While Weatherseal installed thousands of doors and windows each year, they had a reputation for poor quality service and shady sales tactics (highly inflated prices, hard sell lines, and not providing cancellation rights) to attempt to speed up contracts.
The good news is there’s no shortage of professional window installers that you can explore.
Keep reading this guide to learn about these companies’ selling points based on TrustPilot reviews (as of February 2024), their product features, and their history.

What are Good Prices?
Professional window installers can offer many accessories, payment schemes, and warranties, significantly affecting pricing. But what are the reasonable prices to watch out for?
Below is a summary based on the window type.
| Type of Window | Average Cost |
|---|---|
| Bay (3 panels) | £1,190 – £2,700 |
| Bow (4 panels) | £1,430 – £3,240 |
| Casement | £160 – £1,240 |
| Sash | £240 – £1,860 |
| Tilt & Turn | £200 – £1,550 |
These prices will change dramatically depending on the installation, fittings, service, insurance, and other factors. In most cases, the following factors will affect your quote the most.
- Fittings – This can range from 4-8 styles.
- Glass – Stained, Georgian, sandblasted, decorative, obscure, resin, ecoA, and more.
- Frames – Casement, Sash, Tilt & Turn, Bow, and Bay.
- Your Home – Your home will greatly affect the installation cost, which means that you cannot get an accurate quote without an inspection. Details like the condition of your walls, the height of your home, your existing windows, and even the existing frame in the windows will affect installation costs.
It’s always a good idea to decide which types of windows and doors you need and why before you schedule a sales appointment. This will allow you to get a better price and will allow you to avoid pressure sales tactics to upgrade to a more expensive window or model.
Getting a Good Deal from Window Installers
These are the best practices to remember to get the best out of your potential service provider. Remember, the upfront costs can be expensive, so you have to choose wisely.
Get Quotes – Request quotes from other companies in advance so that you know what your project is worth and so you can show the lowest offers to the Weatherseal salesperson.
Recommendations From Family/Friends – There’s no better review than from people you trust the most. Ask around your network, take a look at the finished installations, and ask for negotiation tips and payment schemes that worked best for them.
Plan Your Windows – It’s important to know what you want and why before you meet with a surveyor. Taking the time to conduct research to learn what your installation should be worth can also help you to get a good deal.
Be Careful – Don’t sign anything on the same day! Ask for time to review your contract, and make sure you review your offerings and what’s included (yes, even the fine print). In some cases, you may be asked to pay for mandatory insurance (it’s illegal to require insurance) and other fees, so you should take the time to look these up online.
Review the Work – Take the time to review all work completed by the fitters before signing off on it. If you’re unhappy with the installation, accredited companies should have a FENSA-backed guarantee. Plus, the Consumer Rights Act 2015 protects you from faulty goods or services.
