About our sand mastic in Fawley
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. We’re often asked to deal with weathered mastic on the most exposed windows and tired mastic found when preparing windows for paint, on sash and case windows, brick reveals and timber door frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Fawley is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What the job involves on each surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
What happens on the day
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere like Fawley needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- Mention any tricky access

Advice
Windows and doors in Fawley
Fawley is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Beaulieu Palace House (about 4.4 miles west) are a reminder that the area around Fawley has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Hamble station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Fawley Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Fawley
Will you come out to Fawley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is sand mastic in a coastal place like Fawley 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.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
How long does sand mastic take to go off?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
What affects the quote in Fawley
We do not publish a price list. What we look at:
- The number of rooms or windows
- The size of the job
- When we can work, for business premises
- Whether there’s mould to deal with
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What sealant work cannot fix
We will always be straight with you, so here’s what sealant cannot fix:

- Rotten sashes, sills or window boxes (a joiner’s job)

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Inspect the joints round the windows every year or so
- Sort the mastic before the decorators arrive
- Make sure water runs off the sill
- Ask a joiner to look at soft timber first
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
