Window Mastic in Lymington
Our applicators work in Lymington on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

How we handle window mastic in Lymington
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on uPVC windows, aluminium frames and window sills, and common reasons people get in touch are hard, cracked sealant around windows and rain getting in at the frame or under the sill.
Plenty of homes in a town like Lymington have had conservatories, patio doors or new windows added over the years. Every addition brings more joints, each wearing at its own pace. Leaks normally start at a sill, a frame head or a glazing joint.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Your questions about window mastic in Lymington
Is window mastic in a coastal place like Lymington 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.
Can you help a landlord with a rental near Lymington Town station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
How many windows can you do in a day?
A few frames take a few hours. You will get a timescale with the quote.
Landlord and commercial work in Lymington
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Different surfaces, different methods
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Windows and doors in Lymington
Lymington is close to 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 window and door frames, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St. Thomas the Apostle, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Lymington Town station, renewing tired window mastic between tenants heads off draught and damp complaints.

Why it’s worth doing now in Lymington
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Around Lymington, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- Every job guaranteed for a year
- A choice of colours where the product allows
- Colour picked to suit the job
- More than 20 years in sealant work

Do you need window mastic in Lymington?
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
Signs it’s time to call us include:
- Untidy mastic left by window fitters
- Leaking joints at the ends of sills
- A bead that doesn’t match the frame
- Water coming in at the bottom corners of a door
If you look after a building such as Lymington Junior School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
