Sand mastic in Brighton Hill
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Common call-outs are for tired mastic found when preparing windows for paint and failed mastic on an exposed elevation, on period & listed homes, stone surrounds and sash and case windows.
Around Brighton Hill, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
You get a one-year guarantee, the same in Brighton Hill as everywhere else we work.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
If you manage several properties in or around Brighton Hill, several properties can go on one quote. Send us the addresses and the work at each.
When to call us in Brighton Hill
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
The problems people usually mention when they call are:
- Mastic dropping out of the joint
- Old cement repairs round a window that have failed
- Tired mastic found when preparing windows for paint
- Open joints round the window box
Letting a property close to Basingstoke station? Then any sash windows need sound mastic to keep draughts and rain out.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What affects the cost of sand mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- The size of the job
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Which sealant suits the joint
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.
Asking for a quote
What to tell us when you ask for a quote:
- Whether it’s a home or a business
- The address or postcode of the job
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
What sealant work can’t fix
We will always be straight with you, so here’s what new sealant won’t do:
- Planning or listed building consent (your local planning authority decides)
- Sashes that need overhauling
- Broken panes
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.
Joints and surfaces we work on
- Timber door frames
- Stone surrounds
- Period & listed homes
- Tenement windows

Why it’s worth doing now in Brighton Hill
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Homes in smaller places like Brighton Hill can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Anti-fungal sanitary silicone in wet areas
- Arbo and Everbuild products
- More than 20 years in sealant work

How the visit works
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. In a smaller place like Brighton Hill, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Windows and doors in Brighton Hill
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. Historic houses like The Vyne (about 4 miles north) are a reminder that the area around Brighton Hill 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 is traditional sand mastic.
If you look after a building such as Brighton Hill Community School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as The Church Of Christ The King, the joint between an old wall and a newer frame is generally the first place rain gets in.
