Should I try a DIY kit first?

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

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.

uPVC repair in Llwyngwril, done in place

We also do snagging repairs for builders. We fill and refinish the damage to match the frame, including woodgrain finishes. Whether it’s scratches from ladders and furniture and burns on sills, we can help.

We guarantee the work for a year. If something is not right in that time, we come back and put it right. Warm soapy water and a soft cloth are all it needs. Avoid solvents and abrasive cleaners.

Questions from Llwyngwril

Which areas do you work in?

We work UK-wide, so Llwyngwril is covered. Prices don’t change with location.

When can you do it?

We will give you dates with your quote. Tell us if you need it done quickly.

Is it worth repairing rather than replacing?

Generally, yes. A repair skips the removal, fitting and redecorating. If it is not worth repairing, we will tell you.

Is my repair covered?

Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.

Are you a vetted contractor?

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

Is it messy?

Very little mess: we sheet and mask everything nearby, and we take our waste away with us.

What happens after I send photos?

You get a fixed quote and available dates. If anything’s unclear, we will ask for another photo.

Do I have to be there?

We need someone to let us in. After that, you can carry on with your day.

What happens on the day

Your technician turns up when we said we would and checks the damage against your photos first. The floor and nearby surfaces are covered before any work starts. Most visits take a morning or an afternoon, and we leave the room as we found it.

  1. First the frame or panel is cleaned.
  2. Next we fill the damage.
  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.

How to prepare

  • Tell us if there are stairs or a lift
  • Clear toiletries, mats and anything else from around the area
  • Mention any parking restrictions or tricky access

How to get a price

To get a price, send two or three pictures through our quote form or ring us. We will say straight away whether it can be repaired.

Advice

Repairing versus replacing in Llwyngwril

A new window, door or sill costs far more, and it may not match the rest after years of weathering. A repair leaves the unit in place. Prices start from £95. Rather than charging by the hour, we price the whole job up front. It depends on the damage, the material and access.

Why us?

  • One price list for the whole UK
  • We’ll tell you if it’s not worth repairing
  • Most jobs done in one visit
  • Everything repaired in place

Read our prices page.

What we cannot put right

We’ll always be straight with you, so here’s what a repair won’t do:

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

Send us pictures and we will tell you honestly.

Surfaces we repair

  • Conservatory frames
  • White uPVC
  • Coloured and woodgrain uPVC

Work for landlords and builders

We also carry out snagging repairs for builders and developers, fixing chips and scratches before handover. We hold CHAS, Constructionline and SafeContractor accreditations.

Rental properties take more wear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.

How we price uPVC repair

Repairs from £95. There is no area surcharge for Llwyngwril. What changes the price is:

  • The material
  • Previous DIY repairs that have to come out
  • How much damage there is
  • Unusual colours or finishes

The price depends on the type and amount of damage, the material and how many jobs we combine into one visit. You get a fixed quote from your photos, so there are no surprises on the day.

Getting a price from photos

Most quotes are done from photos alone. To make it quick:

  • Details of any past repairs
  • One picture of the entire window, door or sill
  • Natural light rather than flash
  • A coin or ruler next to the damage for scale

Call 0345 017 0787 or use the quote form. With one close-up and one wider picture, we can price the job.

Common problems we fix in Llwyngwril

uPVC is tough but not indestructible: ladders, tools and building work scratch and chip it, candles and cigarettes burn sills, and removed fittings leave holes.

Most people contact us after spotting one of these:

  • Damage during building work
  • Holes from removed fittings and alarms
  • Scratches from ladders and furniture
  • Chips and dents

Comparing quotes

  • Whether the price is fixed and includes VAT
