Need uPVC repair in Thornhill?

How it works

On the day, the technician arrives at the agreed time, protects the room with dust sheets and masking and gets started. Expect it to take a morning or an afternoon. We tidy up before we leave and tell you when it’s ready to use.

  1. We clean the frame or panel.
  2. We fill scratches, chips and holes.
  3. The repair is sanded smooth.
  4. The finish is colour matched, woodgrain included.
  5. The repair is blended into the surface around it.

How to prepare

  • Mention any earlier repairs or resurfacing
  • Clear toiletries, mats and anything else from around the area
  • Have somewhere for us to park nearby if possible

Advice

uPVC repair in Thornhill, done in place

The damage is filled and refinished so it blends into the frame, including woodgrain finishes. Builders and developers use us for snagging repairs too. If you’re dealing with burns on sills and holes from removed fittings and alarms, we can help.

You are covered for a year from the day of the repair. Just call us if there is a problem and we will sort it. Warm soapy water and a soft cloth are all it needs. Avoid solvents and abrasive cleaners.

Repair or replace in Thornhill?

Replacing the frame or sill costs far more, and new uPVC may not match the weathered frames around it. Repairing the damage keeps the original. Our uPVC repair starts from £95. No two jobs are quite the same, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.

Why Thornhill customers choose us

  • A year’s guarantee on all work
  • Fixed prices from your photos

  • Colours mixed by hand to suit your surface

Thornhill questions

When can you do it?

Your quote comes with available dates. Tell us if you need it done quickly.

What do you need from me?

Just photos, your postcode and a contact number. On the day, access to the room.

Can a burnt window sill be fixed?

Yes. The burn is filled and refinished to match.

Is a repair better than a new one?

Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.

Will the price change on the day?

Your quote covers the damage in the pictures. Anything extra is discussed before we begin.

I rent my home. Can I book you?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Is there any odour?

Some materials have a smell while they’re applied, so we ventilate the room. It clears as the materials cure.

Can I get a quote without a visit?

Nearly always. We only ask to see it in person if the photos can’t show what we need.

Should I try a DIY kit first?

What a professional repair adds is preparation, colour matching and finishing. 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.

We understand the appeal of fixing it yourself. The trouble is that kit repairs frequently look fine at first and then fail, and then the old filler has to be removed first.

Landlord and trade work in Thornhill

Hotels, guest houses and holiday lets can’t afford rooms out of action for long, so we keep visits short and tidy. We will fit around changeovers where we can.

Rented homes see more wear and tear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.

Do you need uPVC repair in Thornhill?

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

Contact us if you’ve noticed any of these:

  • Scratches from ladders and furniture
  • Burns on sills
  • Chips and dents
  • Holes from removed fittings and alarms

Questions to ask before you book

  • Whether a trained technician does the job
  • What preparation is included
  • How the room is protected while they work
  • Is the price fixed, and does it include VAT?

Our hiring checklist

What uPVC repair costs

Repairs from £95. We give every job a fixed quote from photos. This is what makes a difference:

  • Unusual colours or finishes
  • What kind of damage it is
  • Doing more than one item at once
  • Whether old repairs or coatings need taking off

Instead of hourly rates, we fix the price before we start. Damage, material and access decide it.

Quotes from your photos

When you take your pictures, a few simple things make all the difference:

  • Something in shot to show the size
  • Details of any past repairs
  • The postcode, so we can plan the visit
  • One picture of the entire window, door or sill

You do not need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed quote.

What a repair cannot fix

A repair isn’t always the answer, and we’ll tell you before we start. We can’t fix:

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

If in doubt, send pictures and we’ll say what we think before booking.

Materials we work on in Thornhill

  • Window frames & sills
  • Coloured and woodgrain uPVC
  • White uPVC
