DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Sand mastic for homes and businesses in Water Eaton
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. Common call-outs are for a silicone bead on a sash window that spoils the look and old cement repairs round a window that have failed, across period & listed homes, tenement windows and brick reveals.
In a smaller place like Water Eaton, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
There’s a 12-month guarantee on every job, large or small.

Frames and glazing around Water Eaton
With historic houses such as Bletchley Park (about 1 mile north-west) nearby, there’s older building stock in the area around Water Eaton as well as newer homes. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Bletchley station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Water Eaton Church Centre, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens if it’s left?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. In a smaller place like Water Eaton, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

Signs you need sand mastic in Water Eaton
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
If you can see any of these, it’s time to have the joints looked at:
- Modern sealant on a period surround
- Window mastic to renew ahead of painting
- Mastic round period door frames that has failed
- Failed mastic on an exposed elevation
If you look after a building such as The Premier Academy, its window and door frames need their mastic kept sound, just like a home’s.

Quotes for sand mastic in Water Eaton
There’s no set price list, because jobs vary so much. The quote depends on:
- Any working-time requirements on site
- Which sealant suits the joint
- The number and length of the joints
- The old material and how stubborn it is
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How to look after the new joints
To keep the joints looking good and working properly:
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long does sand mastic take?
Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee, and we’re fully insured.
