Window mastic in Worting
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. If you have mastic that has split away from the wall and mastic that’s falling out in pieces, we can put it right, whatever the surface.
Around Worting, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
All our work comes with a one-year guarantee, wherever you are in Hampshire.

When to call us in Worting
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- Mastic that has split away from the wall
- Cold air getting in at the frame edge
In the older streets around Church of St Thomas A Becket, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
- How long the guarantee is
- Who turns up on the day
How the job changes by surface
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
What affects the cost of window mastic
Your quote is based on your job. We look at:
- How easy the joints are to reach
- How many areas need sealing
- The product the joint needs
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

When you contact us, it’s useful to know:

Questions from Worting
Do you cover Worting for window mastic?
Yes. We work across London and the South East, and Worting is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Basingstoke station?

Can you match the sealant to my frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Is the new sealant paintable?
That depends on the product. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before any work starts.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What does window mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What window mastic looks like in Worting
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. With historic houses such as The Vyne (about 3.7 miles north-east) nearby, there’s older building stock in the area around Worting as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Basingstoke station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Chiltern Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What else we do in Worting
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Homes in smaller places like Worting can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or email us.

How it works
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. In a smaller place like Worting, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or send us an email.
