How the visit works
Expect a friendly, tidy visit. We confirm the time with you beforehand, protect the area, and get on with the job, which normally takes a few hours. If we find something your pictures didn’t show, we’ll explain it before carrying on. For a home in Knebworth, we normally park close by and start immediately.
- First the frame or panel is cleaned.
- Scratches, chips and holes are filled.
- We sand the repair smooth.
- We colour-match the finish, including woodgrain effects.
- The repair is blended into the surface around it.
Preparing for the visit
- Keep pets and children out of the room while we work
- Have a window or extractor fan available
- Have somewhere for us to park nearby if possible
Getting a price
Pricing is simple: take a close-up of the damage and a photo from further back, send them to us with your postcode, and you’ll get a fixed price back. There’s no charge for the quote and no obligation.

Questions from Knebworth
Do you work for schools and businesses in Knebworth?
Yes. We hold CHAS, Constructionline and SafeContractor accreditations and work for schools, leisure centres and businesses. We’ll agree timings that suit the building.
Do you work for landlords with property near Knebworth station?
Yes. We repair windows, doors and sills between tenancies for landlords and letting agents, and we can quote for several properties together.
Is it messy?
Very little mess: we sheet and mask everything nearby, and we take our waste away with us.
Which areas do you work in?
All of Hertfordshire, and the rest of the UK. Travel is included in the price.
How soon can you come?
Your quote comes with available dates. Tell us if you need it done quickly.
Do you cover Knebworth?
Yes, we do. Repair technicians travel to Knebworth from across the region, and the price is the same as everywhere else.
Do I have to be there?
We need someone to let us in. You do not need to watch us work.
What happens once I’ve sent pictures?
We look at the photos and reply with a fixed price and some dates. If we need another angle, we will ask.
DIY repairs versus a professional job
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
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, and the work is guaranteed.
Why repair rather than replace?
Replacing the frame or sill costs far more, and it may not match the rest after years of weathering. Repairing the damage leaves the unit in place. For a home around Knebworth where the window, door or sill is sound, replacing it is rarely worth the cost and disruption.
Prices start from £95. Set against the cost of replacement, a repair is normally a fraction of the price, because nothing has to be taken out, refitted or made good. The quote lists exactly what you’re paying for.

When to call us in Knebworth
uPVC is hard-wearing, but it does get damaged: ladders, tools and building work scratch and chip it, candles and cigarettes mark sills, and removed fittings leave holes.
The most common problems we’re called about are:
- Holes from removed fittings and alarms
- Damage during building work
- Chips and dents
- Scratches from ladders and furniture
Rented homes near Knebworth station (in Knebworth itself) change hands frequently, and repairing windows, doors and sills between tenants is quicker than replacing them.

What uPVC repair costs
Repairs from £95. There are no hourly rates or hidden extras. The price depends on:
- Doing more than one item at once
- Previous DIY repairs that have to come out
- Unusual colours or finishes
- Access to the area
Our prices are the same across the UK, so there’s no premium for Knebworth. What changes the price is the job itself: how much damage, what it’s made of and how many items.
How to get a fixed quote
The better the photos, the more accurate the price. Here’s what helps:
- A close-up of the damage, in focus
- One picture of the whole window, door or sill
- A coin or ruler next to the damage for scale
- Your postcode, so we can check dates
A quote takes minutes to ask for: photograph the damage, then the whole window, door or sill, add your postcode and send them over. You will get a fixed price, not an estimate.
Work for landlords and builders
We’re used to working with agents and managing companies. Send the address, photos and access details and we will arrange it.
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.
