Barrowhill Window Mastic
Window and door frames in Barrowhill need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- Whistling draughts around closed windows
Window mastic in Barrowhill, done properly
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have untidy mastic left by window fitters and damp patches on the reveal after heavy rain, we can put it right.
Somewhere as small as Barrowhill, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
- Keep paint and stain on wooden frames in good order
- Air rooms to keep condensation down around windows
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
Your questions about window mastic in Barrowhill
Do you cover smaller places like Barrowhill?
Yes, Barrowhill is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Barrowhill in your area for window mastic?
Yes. We work across London and the South East, and Barrowhill is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
How many windows can you do in a day?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.

What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes most of a day for a typical house, less for a few frames, depending on the amount of work. For a village or hamlet like Barrowhill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

Barrowhill homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Westenhanger Castle (about 1 mile east) nearby, there’s older building stock in the area around Barrowhill as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Westenhanger station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Sellindge Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Barrowhill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

- Rotten timber, which needs a joiner first
- Broken hinges, locks or handles

Different surfaces, different methods
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
