Window Mastic in Clavering
Problem with your window and door frames in Clavering? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Mastic that is falling out in pieces
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
How we handle window mastic in Clavering
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Typical jobs include gaps where the sill meets the wall and gaps between the frame and the inside reveal, across timber windows & doors, composite doors and aluminium frames.
Somewhere as small as Clavering, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our one-year guarantee.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Ventilate rooms so frames don’t stay wet inside
- Clean frames with a soft cloth and soapy water
- Clear any debris from frame drain holes
- Keep solvents and bleach off the sealant
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Look out for the warning signs: 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.

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Timber windows & doors
- Aluminium frames
- Window sills
- Patio & French doors

Surface by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Clavering Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Mary and St Clement, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How it works
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, we protect the area and start. It normally takes most of a day for a typical house, less for a few frames. In a small place like Clavering, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
