UPVC repair in Wenallt

About our uPVC repair in Wenallt

We also do snagging repairs for builders. We fill and refinish the damage to match the frame, woodgrain finishes included. We regularly repair doors & door panels, conservatory frames and coloured and woodgrain uPVC, and common reasons people get in touch are chips and dents and burns on sills.

We stand behind the work with a one-year guarantee, so you’re not left on your own once we’ve gone. Clean with warm soapy water and a soft cloth. Do not use solvents or scourers.

How we price uPVC repair

Repairs from £95. There are no hourly rates or hidden extras. The price depends on:

  • Access to the area
  • The colour and finish to match
  • How much damage there is
  • The type of damage

A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

How to get a fixed price

Photographing the damage takes a minute, and it saves a visit. Please include:

  • Natural light rather than flash
  • A picture taken from further back
  • The postcode, so we can plan the visit
  • The material, if you know it

Getting a quote takes a couple of minutes: take one close-up and one wider shot of the window, door or sill, include your postcode and send them over. You’ll get a fixed price, not an estimate.

Can I fix it myself?

DIY kits are sold for most surfaces, and they can make a small mark look better. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.

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

The process

Nothing needs to be moved out of the room beforehand. We bring everything we need with us, lay protective sheets and get going once we’ve agreed what we are doing. Most jobs take a few hours, and you are welcome to carry on with your day while we work.

  1. We clean the frame or panel.
  2. We fill scratches, chips and holes.
  3. The repair is sanded smooth.
  4. We colour-match the finish, including woodgrain effects.
  5. We blend the repair into the surrounding surface.

Getting ready for the visit

  • Avoid using the area for a few hours before we arrive
  • Plan for the room to be out of bounds to pets and children
  • Mention if the room is upstairs or in a flat

Advice

When to call us in Wenallt

uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes mark sills, and removed fittings leave holes.

It’s worth getting a quote if you see:

  • Damage during building work
  • Burns on sills
  • Chips and dents
  • Scratches from ladders and furniture

Questions to ask before booking

  • How to look after the finish
  • Whether the price is fixed and includes VAT
  • Who will actually do the work
  • How long the guarantee is and what it covers

FAQs for Wenallt

Will you leave a mess?

No. The work area is masked and covered, and we leave the room clean.

Is it safe with children and pets around?

Keep pets and children away from the work area on the day, mainly so nothing gets touched before it has cured.

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.

What do you need from me?

Photos of the damage, a picture of the whole window, door or sill and your postcode. Then we’ll agree a date.

Do you charge for travel?

Travel is included in the price, and we charge the same wherever you are.

Do you hold any accreditations?

Yes. Our accreditations include CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.

Do you work in Wenallt?

Yes. We cover the entire UK and travel to Wenallt and the rest of Gwynedd. Send photos and we will quote, or call 0345 017 0787.

Can you repair something that is been repaired before?

In most cases. The old repair comes out first, so let us know about it.

Repairing versus replacing in Wenallt

A new window, door 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. Prices start from £95. A repair typically costs much less than people expect, especially compared with replacing and refitting. Photos let us give you the exact figure.
