Lymington: your questions answered
Does the coastal weather in Lymington affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Can you do sand mastic in Lymington?
Yes. Our work covers London and the South East, and Lymington is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.
How long does sand mastic take to harden?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
How we handle sand mastic in Lymington
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We work on stone surrounds, brick reveals and timber door frames, and common reasons people get in touch are crumbling sand mastic round a window and modern sealant on a period surround.
In a town like Lymington, 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.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job generally takes a few hours per window, depending on the condition of the joints. In Lymington, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- 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.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions

Advice
Landlords, agents and businesses in Lymington
If you manage several properties in or around Lymington, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

What else we do in Lymington
Sand mastic in Lymington: local notes
Lymington 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’s hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Lymington Junior School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St. Thomas the Apostle, the joint between an old wall and a newer frame is normally the first place rain gets in.

How we quote for sand mastic
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows
- Which sealant suits the joint
- How much there is to do
- Whether there’s mould to deal with
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- If someone has resealed it before
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved.
What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Signs you need sand mastic in Lymington
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Keep an eye out for these signs:
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
- Mastic that needs renewing before redecorating
- Failed mastic on an exposed elevation

- How long to leave it before use
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Ask a joiner to look at soft timber first
- Keep modern sealant off the mastic
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
