UPVC repair near Y Bala

Work for landlords and builders

We also carry out snagging repairs for builders and developers, putting right damage done during fitting. We are CHAS, Constructionline and SafeContractor accredited.

Hotels, guest houses and holiday lets need rooms back in use quickly, so most of our work is done in a single visit. We will fit around changeovers where we can.

uPVC repair in Y Bala, done in place

Builders and developers use us for snagging repairs too. The damage is filled and refinished to match the frame, woodgrain finishes included. If you’re dealing with burns on sills and holes from removed fittings and alarms, we can help, on conservatory frames, white uPVC and doors & door panels alike.

The work is covered for a year after we finish. Just call us if there’s a problem and we’ll sort it. Clean with warm soapy water and a soft cloth. Do not use solvents or scourers.

Repair or replace: which is better?

Replacing the frame or sill is a much bigger job, and it may not match the rest after years of weathering. A repair leaves the unit in place. Our uPVC repair starts from £95. What it costs depends on how much damage there is and what kind, the material and how many items we do on one visit. You get a fixed price from your photos, so there are no surprises on the day.

How the visit works

We agree an arrival time beforehand, so you are not left guessing. On site, it takes a few hours in most cases. We leave the room clean.

  1. We start by cleaning the frame.
  2. We fill scratches, chips and holes.
  3. We sand the repair smooth.
  4. The finish is colour matched, woodgrain included.
  5. Finally we blend it into the rest of the frame.

Before we arrive

  • Have somewhere for us to park nearby if possible
  • Ensure the room can be ventilated
  • Mention if the room is upstairs or in a flat

How to get a price

You do not need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we will reply with a fixed price.

Related advice

DIY kit or professional repair?

We understand the appeal of fixing it yourself. The trouble is that kit repairs often look fine at first and then fail, and then the old filler has to be removed first.

Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is usually cheaper.

Common questions in Y Bala

Is it worth repairing rather than replacing?

In most cases, yes. A repair skips the removal, fitting and redecorating. If it isn’t worth repairing, we will tell you.

Is it OK to have pets in the house?

Please keep children and pets out of the room during the visit. Everywhere else in the home is fine.

What do you need from me?

Some pictures, your postcode and how to reach you. On the day, access to the room.

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

Of course, and it normally saves money. Send pictures of everything together and you’ll get one combined price.

Do you work for landlords and businesses?

Yes. We carry out repairs for householders, landlords, letting agents, builders and businesses.

How do I get a price for uPVC repair in Y Bala?

Repairs from £95. The exact price depends on the damage, so we quote from photos. You’ll get a fixed figure before you book.

Is the work guaranteed?

Yes: twelve months. If there’s a problem with the work in that time, we come back and put it right.

Can you price it without visiting?

In nearly every case. If pictures don’t show enough, we’ll ask for another angle.

What we are called out for in Y Bala

uPVC is hard-wearing, but it does get damaged: ladders, tools and building work scratch and chip it, candles and cigarettes burn sills, and old fittings leave holes.

  • Damage during building work
  • Holes from removed fittings and alarms
  • Scratches from ladders and furniture
  • Burns on sills

Questions to ask before you book

  • Who will actually do the work
  • How to look after the finish
  • If travel is included in the price
  • What the guarantee covers, and for how long

Repairs from £95. Prices are worked out job by job. The main factors are:

The better the pictures, the more accurate the price. Here’s what helps:

  • Natural light rather than flash
  • One sharp close-up of the damage
