Sand mastic in Chapel Row, done properly
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. Common call-outs are for cracked mastic round a front door frame and cement or filler used on old window joints that has cracked, on tenement windows, timber door frames and stone surrounds.
Somewhere as small as Chapel Row, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Frames and glazing around Chapel Row
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Horselunges Manor (about 3.4 miles west) nearby, there’s older building stock in the area around Chapel Row as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Herstmonceux Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Pevensey Bay station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

The process
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Somewhere as small as Chapel Row, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
- Mention any parking rules near the property

Related advice
Do you need sand mastic in Chapel Row?
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.
Any of these means the joints need attention:
- Open joints round the window box
- Draughts and rain around sash boxes
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
Historic houses such as Horselunges Manor, about 3.4 miles west, show how far back building around Chapel Row goes, and older homes nearby need a sealant that suits their walls.
What your quote should include
- Whether all the old sealant comes out first
- How the joint is cleaned and prepared
- Which colour the sealant will be
- Which sealant they’ll use, and why
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Get any rot dealt with first
- Don’t paint over the new mastic
- Avoid heavy scraping on the mastic joint
- Renew mastic before redecorating the windows
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. Painting over failed mastic hides the problem for a while.

Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can landlords and businesses book you?
Yes, regularly. Several properties can go on one quote.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We’ll explain what to expect before we leave.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

Asking for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Whether it has been sealed before
- The type of property
- Roughly how big the job is
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.
Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Older cottages and farmhouses around Chapel Row can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
