Common questions in Old Knebworth
Is it safe with children and pets around?
Yes, as long as they stay out of the room we are working in. We’ll let you know when it’s safe to use again.
Can I add another job to the visit?
Yes. Doing several items on one visit normally costs less than separate visits. Include photos of each item.
Do you work in Old Knebworth?
We do. Repair technicians travel to Old Knebworth from across the region, and the price is the same as everywhere else.
Do you repair coloured uPVC?
Yes. We recreate the colour and grain by hand.
Is there a call-out fee?
Travel is included in the price, with the same prices everywhere we work.
Can I get a quote without a visit?
In nearly every case. If photos do not show enough, we’ll ask for another angle.
Will it make a mess?
Dust sheets and masking go down before we start, and tidy up before we leave.
It’s been repaired before. Can you still fix it?
Typically, yes. The old repair comes out first.
Repair or replace in Old Knebworth?
Replacing the frame or sill costs far more, and it may not match the rest after years of weathering. Repairing the damage keeps the original. Prices start from £95. Our prices are the same across the UK, so there is no premium for Old Knebworth. The job itself decides the price: the material, the amount of damage and how many items.

Related advice
Landlord and trade work in Old Knebworth
Hospitality businesses cannot afford rooms out of action for long, so most of our work is done in a single visit. We will fit around changeovers where we can.
Housing associations and facilities teams use us for planned and reactive repairs. A repair avoids taking out and refitting, which matters when someone is living in the home.
Should I try a DIY kit first?
Kits are cheap and easy to find, but the repairs we redo most often are DIY ones that have discoloured or lifted. Getting it right first time is generally cheaper.
It’s natural to want to try a repair yourself. The trouble is that kit repairs frequently look fine at first and then fail, and the old filler has to come out before a proper repair.
