Sand mastic for homes and businesses in Waterlooville
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Common call-outs are for a silicone bead on a sash window that spoils the look and failed mastic on an exposed elevation, on sash and case windows, period & listed homes and timber door frames.
In a town like Waterlooville, older houses sit alongside newer estates, with windows of every age. All of them depend on a sound bead of mastic between frame and wall.
Our work is backed for twelve months, in Waterlooville and everywhere else we cover.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

Sand mastic in Waterlooville: local notes
Waterlooville is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Warblington Castle (about 4 miles south-east) nearby, there’s older building stock in the area around Waterlooville 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.
For an older house near a landmark such as Saint George's, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Hart Plain Junior School, its window and door frames need their mastic kept sound, just like a home’s.

Waterlooville questions
Can you help a landlord with a rental near Bedhampton station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover Waterlooville for sand mastic?
Yes, Waterlooville is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Should I use sand mastic or silicone?
It depends on the window. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
Common problems we fix in Waterlooville
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Crumbling sand mastic round a window
- Modern sealant on a period surround
- Mastic that needs renewing before redecorating
- Mastic worn away on windows facing the weather
For landlords with property near Bedhampton station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
What your quote should include
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
- How the colour is chosen
- What happens if they find a problem under the old sealant
How the job changes by surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Why act early in Waterlooville
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Waterlooville they get worse with every use. Replacing the sealant now is the simplest fix.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
Why us?
- Quality sealants from Arbo and Everbuild
- 12-month guarantee on every job
- We leave the area clean and tidy
- Old sealant always removed completely

When something else is needed

- Sash cords, weights and draught-proofing of the sashes
- Timber that has rotted
- Whether work needs listed building consent
