How the job changes by surface
Composite doors
Front doors take the weather head on. We pay most attention there.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window mastic for homes and businesses in Springhead
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on patio & French doors, timber windows & doors and uPVC windows, and the jobs we see most are rain getting in at the frame or under the sill and a bead that doesn’t match the frame.
In smaller places like Springhead, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- A door that needs adjusting, rehanging or new seals
- A failed sealed unit that has misted up
- Damp coming through the wall itself rather than the frame joint

Signs you need window mastic in Springhead
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch after spotting one of these:
- Mastic that has split away from the wall
- Untidy mastic left by window fitters
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
In the older streets around Parish Church of St Botolph, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the visit works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a few frames, or a day or more for a whole house. In a smaller place like Springhead, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Advice
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured for the work.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Springhead, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

What window mastic looks like in Springhead
Springhead is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Cobham College (about 4.1 miles south-east) nearby, there’s older building stock in the area around Springhead as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Painters Ash Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Ebbsfleet International station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Your questions about window mastic in Springhead
Does living near the coast affect window mastic in Springhead?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Ebbsfleet International station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Are you insured?
Yes. We are fully insured.
