About our uPVC repair in Harlech

The damage is filled and refinished so it blends into the frame, woodgrain finishes included. Builders and developers use us for snagging repairs too. We regularly repair conservatory frames, doors & door panels and coloured and woodgrain uPVC, and the jobs we see most are chips and dents and burns on sills.

You are covered after we leave: our one-year guarantee applies to every job, and we’ll explain exactly what it covers when we quote. Clean with warm soapy water and a soft cloth. Avoid solvents and abrasive cleaners.

Prices and what affects them

Prices start from £95. There is no charge for travel to Harlech. The price depends on:

  • What kind of damage it is
  • Whether old repairs or coatings need taking off
  • Where the damage is and how we get to it
  • What the surface is made of

A repair usually costs much less than people expect, especially compared with replacing and refitting. Photos let us give you the exact figure.

Send photos for a quote

Photographing the damage takes a minute. Try to send:

  • A close-up of the damage, in focus
  • The material, if you know it
  • A coin or ruler next to the damage for scale
  • Good light, ideally daylight, without flash glare

Pricing is simple: take a close-up of the damage and a photo from further back, send them to us with your postcode, and we will reply with a fixed quote. Quotes are free and no obligation.

Should you replace it?

Replacing the frame or sill is a much bigger job, and it may not match the rest after years of weathering. Repairing the damage leaves the unit in place. Our uPVC repair starts from £95. The price depends on the type and amount of damage, the material and how many items we do on one visit. You get a fixed quote from your pictures, so you know the cost before booking.

DIY repairs versus a professional job

If you are set on a kit, follow its instructions closely, ensure the area is clean and completely dry, and give it the full curing time. If it does not work out, we can still repair it properly.

If you’ve already tried a DIY fix, that’s fine. We take the old repair out and do it properly, so it does not stop a professional repair. Just mention it when you send pictures, as it can add time.

When to call us in Harlech

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

Customers generally contact us about:

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

What your quote should include

  • If travel is included in the price
  • Whether a trained technician does the job
  • How the room is protected while they work
  • What aftercare is recommended

Our hiring checklist

Landlord and trade work in Harlech

We’re used to working with agents and managing companies. Just send photos, the address and how to get access.

Rental properties take more wear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.

When a repair is not the answer

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

Not sure? Send pictures and we will give you a straight answer before you book.

Surfaces we repair

  • Conservatory frames
  • Doors & door panels
  • Window frames & sills
  • White uPVC
  • Coloured and woodgrain uPVC

The process

You do not need to empty the room beforehand. Everything we use comes in the van with us, lay protective sheets and get going once we have agreed what we’re doing. Most jobs take a few hours, and you are welcome to carry on with your day while we work.

  1. We start by cleaning the frame.
  2. We fill scratches, chips and holes.
  3. We sand the repair smooth.
  4. We match the colour, including woodgrain finishes.
  5. Finally we blend it into the rest of the frame.

Preparing for the visit
