UPVC Window & Door Repairs & Installation in Bristol

The UPVC Doctor Southwest repairs windows and doors across Bristol, Bath and the surrounding areas. A broken handle, a door that will not lock, misted double glazing or a draughty seal — we fix it, usually in a single visit. No call-out charge, no deposit on residential work, and a fixed price agreed before we start.

We are a small local team with over 15 years in the trade. When you get in touch, you deal with the person who will actually do the work — not a call centre or a salesperson.

Same-day reply, Monday to Friday, 8am–5pm.

Repair first

Most windows and doors don’t need replacing

A faulty lock, a worn hinge, a blown sealed unit or a dropped door can almost always be repaired at a fraction of the cost of buying new.

We always recommend the cheapest repair that will properly solve the problem. If a repair will do, that is what we do. We will never push a replacement you do not need.

We carry a wide range of genuine, like-for-like branded parts on the van, so most jobs are finished there and then. No waiting weeks for parts.

No. There is no call-out charge and no deposit on residential work. We assess the problem, give you a fixed price, and only then do you decide whether to go ahead.

2026-08-11T17:42:34+01:00

Usually, yes. We carry the most common handles, locks, hinges and seals on the van, so the majority of repairs are completed in a single visit. Made-to-measure glass units take a few days as they are built to order.

2026-08-11T17:42:11+01:00

Rarely. Most problems come down to one failed part — a handle, a lock, a hinge or a sealed unit. Replacing that part is far cheaper than a new window, and we will always tell you honestly when a repair is and isn’t worth it.

2026-08-11T17:41:45+01:00

All of Bristol, Bath, Keynsham and the surrounding areas. If you are not sure whether you are in our patch, send us a message and we will confirm.
