Window mastic in Catmore, done properly
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. Typical jobs include cracked or shrunken mastic around the frame and cracked sealant at the sill ends, on aluminium frames, composite doors and patio & French doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around Catmore is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Clear any debris from frame drain holes
- Wipe condensation off the frames
- Repaint timber before it’s bare
- Use gentle cleaners on frames and sealant
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or email us.
Signs to watch for: 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 Catmore
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Catmore, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Catmore
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Catmore can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Common problems we fix in Catmore
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The problems people usually mention when they call include:
- Cracked sealant at the sill ends
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
In the older streets around Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
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.
Questions from Catmore
Is window mastic in Catmore guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover Catmore for window mastic?
Yes. We work across London and the South East, and Catmore is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Can you do upstairs windows?
Yes, where they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you do the inside joint as well?
Yes. Indoors, we seal between the frame and the plaster or reveal.
What should I tell you?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
