The process

From the moment we arrive, we keep the work contained to the one room. Surfaces nearby are masked off, the job takes a morning or an afternoon, depending on what we find, and we finish by cleaning up and talking you through the result.

  1. First the frame or panel is cleaned.
  2. Scratches, chips and holes are filled.
  3. We smooth the repair.
  4. We match the colour, including woodgrain finishes.
  5. The repair is blended into the surface around it.

How to prepare

  • Plan for the room to be out of bounds to pets and children
  • Tell us about parking, stairs or access
  • Let us know if it has been repaired before

How to get a price

To get a price, send a couple of photos through our quote form or ring us. We’ll say right away whether it can be repaired.

Advice

Should you replace it?

Replacing the frame 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. 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.

Why us?

  • Colours mixed by hand to suit your surface
  • Rooms protected and left tidy
  • CHAS and Constructionline accredited
  • Most jobs done in one visit

Read our pricing.

Can I fix it myself?

If you do try a kit, read the instructions carefully, and do not use it until it has fully cured. If it fails, we can still put it right.

For a hairline mark somewhere you’ll never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.

When we’d advise against a repair

We’d rather lose a job than do one that will not last, so these are the limits:

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

If in doubt, send photos and we’ll say what we think.

Materials we work on in Merthyr Tydfil

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

Landlord and trade work in Merthyr Tydfil

Letting agents often send us photos straight from the inventory. You can have a price before you arrange access, and we liaise with tenants about access if you’d like us to.

Builders use us to fix snagging damage before handover, so there is no need to replace a damaged item at the last minute. Several plots can be done in one visit to keep costs down.

What affects the price in Merthyr Tydfil

Prices start from £95. We price every job individually. The main factors are:

  • How hard the colour is to match
  • How many areas need work
  • What kind of damage it is
  • How many items we do on one visit

A repair generally costs much less than people expect, especially compared with replacing and refitting. Send photos and we will give you the exact figure.

Quotes from your pictures

Before you send pictures, these tips help us give you a firm price:

  • Any details about the material
  • Details of any past repairs
  • A photo taken from further back
  • A close-up of the damage, in focus

Email us a photo of the damage and one of the whole item, with your CF47 postcode, and we’ll reply with a fixed quote.
