How we handle sand mastic in Richborough Port
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on brick reveals, timber door frames and tenement windows, and people most often call us about weathered mastic on the most exposed windows and mastic round period door frames that has failed.
In a village or hamlet like Richborough Port, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

How to look after the new joints
After the cure time, these simple habits help:
- Renew mastic before redecorating the windows
- Have rotten timber repaired before new mastic goes in
- Ask the planning authority about consent for listed or conservation-area homes
- Go gently near the mastic when preparing windows
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Richborough Port questions
Is Richborough Port within the area you cover?
Yes, Richborough Port is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is sand mastic in a coastal place like Richborough Port any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
How long does sand mastic take to harden?
Not straight away. The skin forms first, and the full set comes later, and we will tell you what to expect.
Where do you work from?
We work from Crawley. Our applicators cover Richborough Port, along with the rest of our area.
Can you match the sealant colour?
In most cases you can choose. We’ll explain which colours are available.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Is sand mastic better than silicone for my windows?
It depends on the window. Period windows in stone or brick generally suit sand mastic and newer frames generally get a flexible sealant.

What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that need overhauling
- Damaged stone surrounds
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.

The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. In a small place like Richborough Port, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
How to get a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Windows and doors in Richborough Port
Richborough Port is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air.

Historic houses like Quex Park (about 4.3 miles north) are a reminder that the area around Richborough Port 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.

What else we do in Richborough Port
What happens if it’s left?
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. In a small place like Richborough Port, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
