About our window mastic in Barming Heath
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. Common call-outs are for gaps left after new windows were fitted and rain getting in at the frame or under the sill, across composite doors, patio & French doors and aluminium frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Barming Heath is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months.

When to call us in Barming Heath
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. That is what backing rod is for.
The most common problems we see are:
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Rushed sealant from a window installation
- Rain getting in at the frame or under the sill
Rented homes near East Farleigh 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.

Why act early in Barming Heath
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Barming Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
What you get with us

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Barming Heath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks

How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.

Can I paint over the new sealant?
Not usually, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.

Landlord and commercial work in Barming Heath
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
For anyone letting property in or around Barming Heath, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Frames and glazing around Barming Heath
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Barming Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Margaret, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
