 Trustindex verifies that the original source of the review is Google. We spent months shopping around for quotes, finding some that were extremely expensive and others that seemed suspiciously cheap. In the end, we chose Windows Plus thanks to their no-pressure sales approach. Visiting their branch in person also helped reassure us that we were making the right choice. The installation was excellent, taking just a couple of days, and the fitters were professional, courteous and clearly took pride in their work. There were a couple of minor adjustments needed after installation, along with an issue involving some damaged glass, but every problem was dealt with promptly and without any fuss. Replacing all your windows and doors is a significant investment, so finding a company that makes the entire process straightforward and stress-free is invaluable. Everyone at this branch made the whole experience an absolute pleasure, from start to finish. A huge thank you to everyone involved for all your hard work and excellent service. We couldn’t be happier with the experience and would wholeheartedly recommend Windows Plus!

 Trustindex verifies that the original source of the review is Google. Had our windows and doors replaced 4  years ago and was really pleased with the service and quality of product throughout our experience. We recently had to call on the guarantee for a window that had blown, a couple of emails later and had the window ordered and informed us when the window was available from the manufacturer, they made contact to arrange the replacement, and while here sorted a couple of minor niggles we had. Friendly and efficient service would highly recommend. One of the best calls on guarantee we have had to make.

Frequently Asked Questions

What makes a composite door different from a uPVC door?

A composite door is built from several materials bonded together, rather than a single hollow profile. Typically this means a solid timber or engineered foam core for rigidity and thermal performance, surrounded by an outer skin of impact-resistant uPVC and glass reinforced plastic. The core gives the door a weight and solidity that a hollow uPVC door cannot replicate, and the outer skin is significantly tougher and more resistant to impact.

This construction also delivers better thermal insulation, helping to keep warmth inside and reduce heat loss through the doorway. The visible surfaces are designed to replicate the texture and detail of painted timber, so you get the look of a traditional door with none of the upkeep. If you are weighing up composite and uPVC options and are not sure which suits your home better, we will walk you through the differences honestly during your free survey.

Are composite doors secure?

Yes. Composite doors are fitted with multi-point locking systems as standard, which engage at several points along the frame when the door is closed, distributing the load and making the door far more resistant to forced entry than a single-point lock. The solid core construction adds a rigidity that hollow uPVC or timber doors simply cannot match, so the door resists flexing and twisting under pressure.

The reinforced frame keeps the door square and secure over years of daily use, and the materials used in the outer skin are specifically chosen for their impact resistance. Combined, these features make a composite door one of the most secure front door options available to homeowners. We will walk you through the specific security features included in your chosen door during your free survey.

Will a composite door fade or warp over time?

No. The outer skin of a composite door is engineered to resist prolonged exposure to heat, cold, rain, and UV light. Unlike timber, it does not absorb moisture or expand and contract with the changing seasons, so the door stays square in its frame and continues to close cleanly year after year. The colour runs through the material rather than sitting as a surface coating, which means it cannot peel, chip, or be scratched away to reveal a different colour underneath.

The result is a door that requires no painting, no staining, and very little maintenance beyond an occasional wipe down. A composite door should look as good ten years from now as it does on the day it is fitted, which is part of why they have become such a popular choice for front entrances.

Do I need planning permission to replace my front door?

Replacing a front door with a composite door of a similar size and position falls under permitted development rights, meaning no planning application is required, and you can proceed once you are ready. Exceptions apply to listed buildings and properties in designated conservation areas, where the local planning authority has additional control over changes to a property’s exterior appearance.

If the work forms part of a larger structural project, such as widening the opening or rebuilding a porch, building regulations may also apply. If you are in any doubt about whether your replacement falls within permitted development, we recommend checking with your local planning authority before going ahead. We are happy to talk you through what we know and point you in the right direction when we come out for your free survey.

What guarantee do you offer?

Every composite door we fit comes with a guarantee covering both the product and our workmanship, with the full terms confirmed in writing before installation begins, so you know exactly what is covered and for how long before any work starts. The door itself is guaranteed against warping and discolouration, and the locking hardware and door furniture are covered too.

As a FENSA certified installer, we register every installation, giving you independent consumer protection and formal confirmation that the work meets current building regulations. This registration also acts as documentation you can pass on if you ever sell the property, giving buyers confidence that the work was carried out to the required standard. If anything isn’t right after we finish, we are easy to contact and will fix it.
