Sand mastic in Earls Colne
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We’re often asked to deal with mastic round period door frames that has failed and mastic that needs renewing before redecorating, on tenement windows, period & listed homes and stone surrounds.
Many houses in smaller places like Earls Colne have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Keep modern sealant off the mastic
- Inspect the joints round the windows every year or so
- Keep sills and gutters clear so water drains away
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
How the job changes by surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.

How it works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It generally takes a few hours for a single window, longer for several. A visit to Earls Colne is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
