About our sand mastic in Ramsgate
Across Ramsgate, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you’re dealing with mastic dropping out of the joint and mastic that needs renewing before redecorating, we can put it right, whatever the surface.
In a town like Ramsgate, the windows on the most exposed side of a house take the brunt of the rain, so the mastic there tends to fail first. Checking every frame, not just the obvious one, is time well spent.
There’s a 12-month guarantee on every job, large or small.

Questions from Ramsgate
Can you do sand mastic in Ramsgate?
Yes. We work across London and the South East, and Ramsgate is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
Is sand mastic in a coastal place like Ramsgate any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.

Sand mastic in Ramsgate: local notes
Ramsgate is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Quex Park (about 4.4 miles north-west) nearby, there’s older building stock in the area around Ramsgate as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near St. Luke's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Priory Infant School, its window and door frames need their mastic kept sound, just like a home’s.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
How to look after the new joints
So the new joints stay in good condition:
- Don’t run silicone over sand mastic
- Take care around the mastic when scraping paint
- Get any rot dealt with first
- Check the mastic when you check the paintwork
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
What happens on the day
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work starts. The work generally takes a few hours per window, depending on the condition of the joints. Parking in a town like Ramsgate is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.

- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Common problems we fix in Ramsgate
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
People normally contact us when they notice something like this:
- Old cement repairs round a window that have failed
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
Rented homes near Ramsgate station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
