What we are called out for in Townsend
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
The problems people usually mention when they call are:
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
Managing a site like The Hurst School? Then the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
- How the colour is chosen
- What insurance they hold
Window mastic in Townsend, done properly
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, ring 0345 464 0079 or send us an email with the number of frames and any access details for window mastic in Townsend. We’re often asked to deal with sealant in the wrong colour for the frame and black, perished sealant on frames, on window sills, patio & French doors and composite doors.
In a village or hamlet like Townsend, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What else we do in Townsend
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
FAQs for Townsend
I let a flat near Midgham station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Townsend?
Yes, Townsend is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Do you seal inside as well as outside?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Is the work guaranteed?
Yes. Our one-year guarantee covers every job, inside or out.
Can you get sealant to suit coloured frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep paint off silicone joints
- Repaint timber before it’s bare
- Make sure the drainage slots are not blocked
- Avoid blasting the frames with a pressure washer
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Windows and doors in Townsend
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as The Vyne (about 4.7 miles east) nearby, there’s older building stock in the area around Townsend as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Church of St Catherine, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Midgham station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
