Window mastic for homes and businesses in Three Ashes
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you are dealing with old mastic that has gone black or come away and cold air getting in at the frame edge, we can help, whatever the surface.
Somewhere as small as Three Ashes, 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.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Three Ashes, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.

Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before work begins.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

How to look after the new joints
To keep the joints looking good and working properly:
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
- Wash the frames with mild soapy water
- Ventilate rooms so frames don’t stay wet inside
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or send us an email.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Do you need window mastic in Three Ashes?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Signs it’s time to call us include:
- Black, perished sealant on frames
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
For an older house near a landmark such as Church of St. Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
