Window mastic in Axmansford
Homes in Axmansford have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on uPVC windows, timber windows & doors and patio & French doors, and people most often call us about leaking joints at the ends of sills and rushed sealant from a window installation.
In a village or hamlet like Axmansford, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
All our work is covered by a 12-month guarantee.

Axmansford: your questions answered
Is Axmansford in your area for window mastic?
Yes, Axmansford is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Is Axmansford within the area you cover?
Yes, Axmansford is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we will choose accordingly.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Why it’s worth doing now in Axmansford
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a small place like Axmansford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before work begins.

What affects the cost of window mastic
Jobs vary more than people expect. What affects the quote:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- The product the joint needs
Doing several joints on one visit is usually more efficient than separate visits. We’ll send you a clear quote for the lot.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Photos by email, if that is easy

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
- Damp problems in the wall away from the window
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Windows and doors in Axmansford
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. With historic houses such as The Vyne (about 4.9 miles south-east) nearby, there’s older building stock in the area around Axmansford as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to Church of St Stephen include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as The Hurst School, larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Make sure the drainage slots are not blocked
- Avoid harsh chemicals near the mastic
- Keep paint and stain on wooden frames in good order
- Air rooms to keep condensation down around windows
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Signs you need window mastic in Axmansford
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Draughts coming in around windows and doors
- Cracked or shrunken mastic around the frame
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
For landlords with property near Midgham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
