What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Sashes that rattle, stick or will not open
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Timber door frames
- Brick reveals
- Stone surrounds
- Tenement windows

- Period & listed homes
How we handle sand mastic in Aldrington
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we will explain which is best for yours. Typical jobs include mastic dropping out of the joint and wind and rain getting in round a sash window, on tenement windows, period & listed homes and stone surrounds.
Many houses in smaller places like Aldrington 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.
Your job is guaranteed for a year, as with all our work.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
- Ask us before painting near the mastic
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
What happens if it’s left?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In a smaller place like Aldrington, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

Common questions in Aldrington
Do you cover smaller places like Aldrington?
Yes. Aldrington is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Aldrington affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is the work guaranteed?
Every job comes with our one-year guarantee, and we’re fully insured.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
What should I tell you?
Let us know what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- The type of sealant required
- The number of rooms or windows
- The size of the job
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

The process
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It usually takes anything from a few hours to a full day, depending on how many windows. Parking around Aldrington is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
How to get a quote

Frames and glazing around Aldrington
Aldrington is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Portslade Manor (about 1.4 miles north-west) are a reminder that the area around Aldrington 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.
Rented homes near Portslade station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Hove Junior School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to St Philip's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Aldrington is about 1 mile south-west of Brighton and Hove, in Brighton and Hove. Jobs in Aldrington get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Aldrington is one of 30 towns and villages in Brighton and Hove we cover.
