We also do snagging repairs for builders. We fill and refinish the damage so it blends into the frame, woodgrain finishes included. Common call-outs are for damage during building work and burns on sills, in coloured and woodgrain uPVC, white uPVC and window frames & sills.

All of our repairs are guaranteed for twelve months, and the guarantee is the same wherever you live. If something goes wrong with the work, we come back. Clean with warm soapy water and a soft cloth. Do not use solvents or scourers.

What we’re called out for in Tremadog

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

Common reasons people in Tremadog contact us are:

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

Questions to ask before you book

  • Who will actually do the work
  • How the room is protected while they work
  • Whether the price covers travel
  • What the guarantee covers, and for how long

10 questions to ask before you book

Should you replace it?

A new window, door or sill is a much bigger job, and it may not match the rest after years of weathering. A repair keeps the original. Prices start from £95. No two jobs are quite the same, so each one is priced on its own. The size and type of damage, the material and access all make a difference, and combining jobs on one visit brings the cost down.

What you get with us

  • Honest advice, even when it means no job
  • No need to remove anything
  • Free fixed quotes from pictures

  • Doors & door panels
  • Conservatory frames

How the visit works

We turn up at the time we agreed with you and checks the damage against your pictures first. Dust sheets and masking tape go down before we open a single tin. Most visits take a morning or an afternoon, and we leave the room as we found it.

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

Before we arrive

  • Point us to the nearest place to park
  • Mention if the room is upstairs or in a flat
  • Let the surface dry out before the visit

Should I try a DIY kit first?

A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.

If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.

What affects the price in Tremadog

Repairs from £95. Every quote is fixed and free. What we take into account:

  • What the surface is made of
  • The size and number of damaged areas
  • How hard the colour is to match
  • How easy the damage is to reach

Rather than charging by the hour, we price the whole job up front. Damage, material and access decide it, and doing several items at once reduces it.

Getting a price from photos

Photographing the damage takes a minute. Try to send:

  • Something in shot to show the size
  • The material, if you know it
  • One sharp close-up of the damage
  • A picture taken from further back

If you’re in Tremadog and want a price, pictures are the quickest way: a close-up, a wider shot and your postcode. We reply with a fixed quote and our next available dates.
