What uPVC repair costs

Prices start from £95. Every quote is fixed and free. What we look at:

  • The material and finish
  • Where the damage is and how we get to it
  • Whether old repairs or coatings need taking off
  • Doing more than one item at once

Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Photos let us give you the exact figure.

Quotes from your photos

Two or three clear pictures are generally enough. Try to include:

  • Any details about the material
  • Natural light rather than flash
  • One sharp close-up of the damage
  • Something in shot to show the size

If you are in Cefn Mawr and want a price, the easiest route is pictures: one close up, one from further back, plus your postcode. You will get a fixed quote with dates to choose from.

DIY kit or professional repair?

If you do try a kit, read the instructions carefully and work on a clean, dry surface, and don’t use it until it has fully cured. If it does not work out, we can still repair it properly.

It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.

How it works

We turn up at the time we agreed with you, introduces themselves and checks the damage against your photos first. The floor and nearby surfaces are covered before we open a single tin. Most visits take a few hours, and we leave the room as we found it.

  1. We clean the frame or panel.
  2. Next we fill the damage.
  3. We sand the repair smooth.
  4. We colour-match the finish, including woodgrain effects.
  5. The repair is blended into the surface around it.

Getting ready for the visit

  • Point us to the nearest place to park
  • Clear toiletries, mats and anything else from around the area
  • Plan for the room to be out of bounds to pets and children

Ask for a price

Ring 0345 017 0787, or send us photos through the quote form. With a clear picture of the damage and one of the entire window, door or sill, we can give you a fixed price the same day in most cases.

Repair or replace: which is better?

Replacing the frame or sill is a much bigger job, and new uPVC may not match the weathered frames around it. A repair leaves the unit in place. Repairs from £95, with every job priced individually. We do not add extras on the day. What we quote from your photos is what you pay, unless the damage turns out to be different, in which case we talk to you first.

When we’d advise against a repair

A repair is not always the answer, and we will tell you before we start. Repairs won’t solve:

  • Failed or misted double glazing units
  • Broken locks, hinges or mechanisms
  • Frames that are warped or out of square

If in doubt, send photos and we will say what we think before you book.

Materials we work on in Cefn Mawr

  • Coloured and woodgrain uPVC
  • Window frames & sills

Cefn Mawr questions

Is my repair covered?

Every repair comes with a one-year guarantee. We’ll explain what it covers when we quote.

Is repairing better than replacing?

Generally, when the rest is in good condition. A repair avoids removal and making good. We will tell you honestly if replacement makes more sense.

Do I have to be there?

Someone needs to let us in and show us the job. You do not need to watch us work.

What happens if you find more damage?

If we find something the photos didn’t show, we explain it first. The price only changes if you agree.

Do you do work for letting agents?

Yes, frequently. We quote for multiple addresses and fit around tenancy changeovers.

Can you do more than one item on the same visit?

Yes. Doing several items on one visit typically costs less than separate visits. Include photos of each item.

Do you come to Cefn Mawr?

We do. We send a technician to Cefn Mawr for every job, and the price is the same as everywhere else.

I’m a tenant. Can you help?

Yes, but check with your landlord or agent first. Landlords are frequently glad to have it sorted.
