Why deal with it now?
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. In a small place like Munstead Heath, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

What sand mastic looks like in Munstead Heath
With historic houses such as Loseley Park (about 3 miles north) nearby, there’s older building stock in the area around Munstead Heath as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Busbridge Infant School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Godalming station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Related advice
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Aftercare tips
So the new joints stay in good condition:
- Get any rot dealt with first
- Do not run silicone over sand mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Do not paint over the new mastic
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.

What we’re called out for in Munstead Heath
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
The problems people usually mention when they call are:
- Cracked mastic round a front door frame
- Cement or filler used on old window joints that has cracked
- Draughty sash windows at the surround
- Mastic that needs renewing before redecorating
For an older house near a landmark such as St John the Baptist Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
