Window mastic for homes and businesses in Whitewood
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. We work on patio & French doors, timber windows & doors and window sills, and common reasons people get in touch are old mastic that has gone black or come away and rain getting in at the frame or under the sill.
Homes in small places like Whitewood often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, large or small.

Whitewood questions
Can you help a landlord with a rental near Godstone station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Can you do window mastic in Whitewood?
Yes. We work across London and the South East, and Whitewood is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we are fully insured.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can I paint over the new sealant?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Tell us if you are decorating and we’ll choose accordingly.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Whitewood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Whitewood homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Godstone station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What affects the quote in Whitewood
You’ll get a clear quote before any work starts. It takes into account:
- Access and height
- The product the joint needs
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- The problem you’ve noticed
- The address or postcode of the job
- Access, such as stairs, a lift or height
There’s no standard price list. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or send us an email.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What we cannot put right
We will always be straight with you, so here’s what sealant can’t fix:
- Condensation trapped between the panes
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Looking after it afterwards
Aftercare is simple:
- Keep paint and stain on wooden frames in good order
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
- Look round the frames every year or so
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
