DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How we handle window mastic in Lane End
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you have rushed sealant from a window installation and gaps where the sill meets the wall, we can help, whatever the surface.
Houses in smaller places like Lane End can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
Whatever the size of the job, you get the same one-year guarantee.

Frames and glazing around Lane End
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as West Wycombe Park House (about 1.9 miles north-east) nearby, there’s older building stock in the area around Lane End 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.
Rented homes near High Wycombe station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Lane End Primary School, its window and door frames need their mastic kept sound, just like a home’s.

- Condensation trapped between the panes
- A door that needs adjusting, rehanging or new seals

Lane End: your questions answered
Will you come out to Lane End?
Yes, Lane End is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near High Wycombe station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.
What does window mastic cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Different surfaces, different methods
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it.
How we quote for window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many areas need sealing
- Access and height
- The size of the job
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
To help us quote quickly, please include:
- If someone has resealed it before
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
What we’re called out for in Lane End
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Look out for these signs:
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
- Hard, cracked sealant around windows
- Cracked internal joints between frame and plaster
If you live in an older home near Church of the Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Leave it or put it right?
Resealing frames is a short job: the visit takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Homes in smaller places like Lane End 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.
Combining jobs into one visit usually makes better use of the time than several visits. We will send you a clear quote for the lot.

How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes most of a day for a typical house, less for a few frames. Parking around Lane End is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Tell us about any water getting in
- Mention any tricky access
- Clear items away from the joints we’re working on
