Sand Mastic in Lower Earley
Sand mastic across Lower Earley and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Patchy fillers round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
- Modern sealant on a period surround
Keeping the joints in good condition
After the cure time, these simple habits help:
- Get any rot dealt with first
- Do not paint over the new mastic
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
Sand mastic in Lower Earley
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on timber door frames, period & listed homes and brick reveals, and common reasons people get in touch are mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look.
Many houses in smaller places like Lower Earley 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. For a job in Lower Earley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- 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
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

Common problems we fix in Lower Earley
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber and we normally remove them.
Common reasons people contact us include:
- Failed mastic on an exposed elevation
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
- Wind and rain getting in round a sash window
Homes close to Trinity Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Leave it or put it right?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Around Lower Earley, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.
