Window mastic for homes and businesses in Upper Woolhampton
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on aluminium frames, window sills and patio & French doors, and the jobs we see most are whistling draughts around closed windows and leaking joints at the ends of sills.
Homes in small places like Upper Woolhampton 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Aftercare tips
Looking after new joints is easy:
- Clean frames with a soft cloth and soapy water
- Avoid harsh chemicals near the mastic
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Upper Woolhampton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Do you need window mastic in Upper Woolhampton?
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That is what backing rod is for.
Any of these means the joints need attention:
- Leaking joints at the ends of sills
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
If you let a flat or house near Midgham station, renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- Whether all the old sealant comes out first
- How long the guarantee is
- Whether they’re fully insured
- Who does the work, and how experienced they are
Questions from Upper Woolhampton
Can you help a landlord with a rental near Midgham station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is Upper Woolhampton in your area for window mastic?
Yes. Our work covers London and the South East, and Upper Woolhampton is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
How long will my window job take?
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.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a small place like Upper Woolhampton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Frames and glazing around Upper Woolhampton
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Woolhampton C.E. Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Douai Abbey Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
