Window & door mastic in Tapnage, Hampshire
Window and door frames in Tapnage need attention? We cut out the old, prepare the joints and apply the right sealant.
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Cracked sealant at the sill ends
How we handle window mastic in Tapnage
Around Tapnage we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have untidy mastic left by window fitters and water coming in at the bottom corners of a door, we can put it right, whatever the surface.
Homes in small places like Tapnage often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All our work is covered by our one-year guarantee.

What affects the cost of window mastic
The quote reflects the job in front of us. We take into account:
- The number of rooms or windows
- The product the joint needs
- Whether old sealant or filler has to be cut out
- The number and length of the joints
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- Whether it’s a home or a business
- If someone has resealed it before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or send us an email.
Tapnage homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Swanwick station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as The Henry Cort Community College, the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards
After the cure time, these simple habits help:
- Air rooms to keep condensation down around windows
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
- Don’t paint over the silicone
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
Tapnage: your questions answered
Do you cover smaller places like Tapnage?
Yes. Tapnage 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.
Do you work for landlords with property near Swanwick station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Will new mastic stop draughts?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Tapnage, the journey is planned in advance: 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.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Getting ready for the visit
- Mention any tricky access
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
For anyone letting property in or around Tapnage, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.
Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Tapnage can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

How the job changes by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
