About our window mastic in Segensworth
From a single sill to a whole house of windows, you’ll get a clear quote before we start. Just phone 0345 464 0079 or email us and tell us how many frames there are and how they’re reached. We work on aluminium frames, patio & French doors and uPVC windows, and people most often call us about cracked or shrunken mastic around the frame and cracked internal joints between frame and plaster.
Around Segensworth, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, whatever its size.

What else we do in Segensworth
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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 fails, we can still redo it.
Questions from Segensworth
Do you cover smaller places like Segensworth?
Yes. Segensworth is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Segensworth affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

Windows and doors in Segensworth
Segensworth 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Cornerstone CofE (VA) Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St John, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Different surfaces, different methods
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep jet washers away from the mastic
- Look round the frames every year or so
- Repaint timber before it’s bare
- Clear any debris from frame drain holes
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Do you need window mastic in Segensworth?
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That is what backing rod is for.
It’s worth asking for a quote if you see:
- Mastic that is falling out in pieces
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
- Draughts coming in around windows and doors
Rented homes near Swanwick station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
