Town Row Sand Mastic
Specialist sand mastic for Town Row: careful preparation, the right product and tidy work. Call for a quick quote.
- Mastic dropping out of the joint
- Draughty sash windows at the surround
- Failed mastic on an exposed elevation
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Avoid patching sand mastic with silicone
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Sand mastic in Town Row
Across Town Row, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. Common call-outs are for modern sealant on a period surround and patchy fillers round a sash window, across period & listed homes, sash and case windows and timber door frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Town Row is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Different surfaces, different methods
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere as small as Town Row, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Your questions about sand mastic in Town Row

Do the sealants smell?

Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How much does sand mastic cost in Town Row?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Common problems we fix in Town Row
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint and we normally remove them.
Common reasons people contact us are:
- Silicone on a period window that looks wrong
- Gaps round a timber door in stone or brick
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
Letting a property close to Crowborough station? Then any sash windows need sound mastic to keep draughts and rain out.

- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- How much experience the applicator has
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Whether work needs listed building consent
- Cracked or broken glass
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Town Row homes and the weather
With historic houses such as Wadhurst Castle (about 4.4 miles east) nearby, there’s older building stock in the area around Town Row as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Rotherfield Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around The Parish Church of St Denys, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
