What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Around Little Bookham, 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.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- Anti-fungal sanitary silicone in wet areas

Sand mastic in Little Bookham
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We’re often asked to deal with patchy fillers round a sash window and gaps between timber frames and stone or brick, on tenement windows, stone surrounds and period & listed homes.
Houses in smaller places like Little Bookham can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
All our work comes with a 12-month guarantee.

DIY versus a professional finish
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 doesn’t work out, we can still put it right.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Little Bookham questions

Can you help a landlord with a rental near Bookham station?

Do you remove the old sealant?

Do you have insurance?

Can old silicone round a sash window be swapped for sand mastic?

Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to a full day, depending on how many windows. In a smaller place like Little Bookham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on
Getting a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Frames and glazing around Little Bookham
With historic houses such as Polesden Lacey (about 1.1 miles south-east) nearby, there’s older building stock in the area around Little Bookham as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Howard of Effingham School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Bookham station, any sash windows need sound mastic to keep draughts and rain out.

When to call us in Little Bookham
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
The most common problems we see are:
- Draughty sash windows at the surround
- Failed mastic on an exposed elevation
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
In the older streets around Church of St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include

- What happens if they find a problem under the old sealant
- Are they insured?
- How the joint is cleaned and prepared
