What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. In a small place like Akeley, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height

Advice
Akeley questions
Is sand mastic in Akeley guaranteed?
All our work, in Akeley and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover Akeley for sand mastic?
Yes. We work across London and the South East, and Akeley is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can you replace silicone on a period window with sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Avoid patching sand mastic with silicone
- Have rotten timber repaired before new mastic goes in
- Check with your local planning authority if your home is listed
- Go gently near the mastic when preparing windows
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Why deal with it now?
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. Where a wall is exposed, as many are in small places like Akeley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Why Akeley customers choose us
- Anti-fungal silicone where joints get wet
- Domestic, commercial and hotel work
- We are fully insured
- We never seal over old sealant

How the job changes by surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is normally favoured.
Work for landlords, hotels and businesses
If you manage several properties in or around Akeley, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Should I try it myself first?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Akeley homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Stowe House (about 2.1 miles west) are a reminder that the area around Akeley has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to Church of St Mary (Assumption of the Blessed Virgin Mary) include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Akeley Wood Senior School? Then its window and door frames need their mastic kept sound, just like a home’s.
