How we handle sand mastic in North Fambridge
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you’re dealing with mastic that needs renewing before redecorating and gaps round a timber door in stone or brick, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in North Fambridge is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with a 12-month guarantee.

Different surfaces, different methods
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Somewhere like North Fambridge needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive

Do you need sand mastic in North Fambridge?
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Any of these means the joints need attention:
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
- Crumbling sand mastic round a window
- Gaps between timber frames and stone or brick
Homes close to Holy Trinity Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Can I do it myself?
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 fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ask us before painting near the mastic
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
