Prices and what affects them
Prices start from £95. You’ll know the full cost before booking. We take into account:
- Doing more than one item at once
- How many areas need work
- How hard the colour is to match
- How easy the damage is to reach
Compared with replacing, repairing typically costs far less, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.
Send pictures for a quote
Phone pictures are fine. Just make sure we can see:
- Daylight if possible, and no flash reflection
- Your postcode, so we can check dates
- One picture of the entire window, door or sill
- What it’s made of, if you know
For most jobs, pictures are all we need to give you a price. Tell us what happened and where you are, and we will reply with a fixed quote and the earliest dates we have.
What happens on the day
Nothing needs to be moved out of the room beforehand. We bring everything we need with us, put protection down and get going once we’ve agreed what we’re doing. It typically takes a few hours, and you’re welcome to carry on with your day while we work.
- First the frame or panel is cleaned.
- Scratches, chips and holes are filled.
- The repair is sanded smooth.
- The finish is colour-matched, woodgrain included.
- We blend the repair into the surrounding surface.
Preparing for the visit
- Have a window or extractor fan available
- Keep a parking space free if you can
- Avoid using the area for a few hours before we arrive
How to get a price
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. What comes back is a fixed price, not a guess.
Advice
DIY kit or professional repair?
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.

Why repair rather than replace?
A new window, door 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. It helps to know what pushes a price up or down: access, material, the extent of the damage and whether we can do several items together. Photos let us give you a fixed figure.

Llanbrynmair: your questions answered
How soon can you come?
We’ll give you dates with your quote. Tell us if you need it done quickly.
Can I add another job to the visit?
Yes, and it’s frequently cheaper. Send pictures of everything together and we’ll quote them together.
Can you match woodgrain uPVC?
Yes. Colour and grain are matched by hand.
Do the materials smell?
It depends on the job, but frequently a little. Ventilation keeps it to a minimum, and it soon fades.

Yes: twelve months. If anything goes wrong with the repair within the year, we return to fix it.
Do you work for landlords and businesses?
We do, regularly. We quote for multiple addresses and fit around tenancy changeovers.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure the landlord agrees.
Are you accredited?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
