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 keeps the original. Prices start from £95. We don’t add extras on the day. The price we quote from your pictures is the price you pay, unless the damage turns out to be different, in which case we talk to you first.

Questions from Llanwnda

What happens after I send photos?

We review the pictures and send a fixed quote with dates.

Is there any odour?

Some materials have a smell while they’re applied. It fades as everything cures.

Do you repair coloured uPVC?

Yes. We recreate the colour and grain by hand.

What areas do you cover?

We work UK-wide, and that includes Llanwnda. Our prices are the same everywhere.

Is it safe with children and pets around?

We ask you to keep children and pets out of the room while we work. The rest of the house is unaffected.

Can I get a quote without a visit?

Yes, almost always. A close-up and a wider photo are enough to give a fixed price.

How soon can you come?

It depends on the time of year and where you are. Send photos with your postcode and we’ll reply with the earliest dates.

Do I have to be there?

Yes. The technician needs access to the room for the visit, at a time we agree with you.

For landlords and businesses

We regularly price jobs from inventory or check-out photos. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.

Hospitality businesses need rooms back in use quickly, so we keep visits short and tidy. We can work around your bookings.

Common problems we fix in Llanwnda

uPVC is hard-wearing, but it does get damaged: ladders and building work leave scratches and chips, candles and cigarettes burn sills, and removed fittings leave holes.

Send us a picture if you notice any of these:

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

Questions to ask before booking

  • Whether the colour is mixed to match
  • How long the guarantee is and what it covers
  • Is the price fixed, and does it include VAT?
  • How long it needs to cure

Choosing a repair company

What we cannot put right

We’d rather lose a job than do one that will not last, so here’s what a repair cannot put right:

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

Send us pictures and we’ll tell you honestly.

Surfaces we repair

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

What we do, step by step

We agree an arrival time beforehand, so you’re not left guessing. On site, it takes a few hours in most cases. The room is left tidy and ready to use once it has cured.

  1. First the frame or panel is cleaned.
  2. We fill scratches, chips and holes.
  3. We smooth the repair.
  4. We colour-match the finish, including woodgrain effects.
  5. The repair is blended into the surface around it.

How to prepare

  • Have somewhere for us to park nearby if possible
  • Move bottles, mats and clutter away from the area
  • Tell us if there are stairs or a lift

Ask for a price

Getting a price is easy: snap the damage close up and then the entire item, send them over with your postcode, and you’ll get a fixed quote back. Quotes are free and you’re under no obligation.

Advice

Prices and what affects them

Prices start from £95. There’s no area surcharge for Llanwnda. What changes the price is:

  • Where the damage is and how we get to it
  • How many areas need work
  • The type of damage
  • Any earlier repairs that need removing first

Rather than charging by the hour, we fix the price before we start. Damage, material and access decide it.

Getting a price from pictures

You can take the pictures on your phone, there is no need for anything special. Just ensure we can see:

  • Your postcode, so we can check dates
  • What it’s made of, if you know
  • Something in shot to show the size
  • A close-up of the damage, in focus

A quote takes minutes to ask for: photograph the damage, then the whole window, door or sill, include your postcode and send them to us. What comes back is a fixed price, not a guess.

Should I try a DIY kit first?

You can buy a DIY kit for most repairs, and they can make a small mark look better. The trouble is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair will not last.

The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
