How we handle sand mastic in Moulsoe
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. If you have mastic round period door frames that has failed and patchy fillers round a sash window, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around Moulsoe is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

How the job changes by surface
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
What happens if it’s left?
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a small place like Moulsoe, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
- Check with your local planning authority if your home is listed
- Clear gutters so water doesn’t pour onto the windows
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours per window, depending on the condition of the joints. Somewhere like Moulsoe needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Advice
Moulsoe homes and the weather
With historic houses such as Linford Manor (about 3.4 miles west) nearby, there’s older building stock in the area around Moulsoe 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. 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 an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Woburn Sands station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
