What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Decisions on consent for listed homes
- Sashes that rattle, stick or won’t open
- Broken panes

Sand mastic for homes and businesses in Emmbrook
We work across Emmbrook renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have failed mastic on an exposed elevation and mastic dropping out of the joint, we can help.
In smaller places like Emmbrook, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

What happens if it’s left?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. In an older home around Emmbrook, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
- Clear gutters so water does not pour onto the windows
- Ask us before painting near the mastic
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Frames and glazing around Emmbrook
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Wokingham station, any sash windows need sound mastic to keep draughts and rain out. In the older streets around Woosehill Community Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Emmbrook Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What affects the quote in Emmbrook
There’s no set price list, because no two jobs are the same. The quote depends on:
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- The number and length of the joints
- Whether the work is at height
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.

Questions from Emmbrook
Will you come out to Emmbrook?
Yes. Emmbrook is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Wokingham station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
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 doesn’t work out, we can still put it right.
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.
The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. A visit to Emmbrook 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.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Mention any sign-in or site rules at work premises
- Clear the area around the work
- Tell us about any water getting in

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or send us an email.
Advice
Different surfaces, different methods
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
