Window Mastic in Leverton
We cover Leverton for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
- Black, perished sealant on frames
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we handle window mastic in Leverton
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. If you have black, perished sealant on frames and rushed sealant from a window installation, we can put it right, whatever the surface.
Homes in small places like Leverton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months, in Leverton and everywhere else we cover.

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Older cottages and farmhouses around Leverton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Clean frames with a soft cloth and soapy water
- Keep drainage slots and sill grooves clear
- Keep paint off silicone joints
- Keep solvents and bleach off the sealant
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. Somewhere like Leverton needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions

Windows and doors in Leverton
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Ramsbury Manor (about 4.6 miles west) nearby, there’s older building stock in the area around Leverton 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.
Rented homes near Hungerford station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like Chilton Foliat Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
