Sand mastic for homes and businesses in Tulse Hill
We work across Tulse Hill renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you’re dealing with patchy fillers round a sash window and gaps where the frame meets the masonry, we can put it right.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Tulse Hill.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What sealant work cannot fix
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Decisions on consent for listed homes
- Sashes that need overhauling
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.

What else we do in Tulse Hill
Surface by surface
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is generally favoured.
Looking after it afterwards
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
- Keep modern sealant off the mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to a full day, depending on how many windows from start to finish. In a London area like Tulse Hill, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- 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.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints

Advice
Frames and glazing around Tulse Hill
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
As a London address, Tulse Hill can be tricky for parking: let us know about parking bays, permits or a driveway. Letting a property close to Tulse Hill station? Then any sash windows need sound mastic to keep draughts and rain out.

Quotes for sand mastic in Tulse Hill
Every job gets its own quote. These are the things that affect it:
- Access and height
- Whether there’s mould to deal with
- The product the joint needs
- How many areas need sealing
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before

Do you need sand mastic in Tulse Hill?
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
- Mastic that needs renewing before redecorating
- Open joints round the window box
If you look after a building such as St Martin-In-The-Fields High School for Girls, the mastic around its windows and doors needs looking after like any other building’s.
