Window Mastic in Lee-on-the-Solent

What the job involves on each surface
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Window mastic in Lee-on-the-Solent, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you have mastic that’s falling out in pieces and damp patches on the reveal after heavy rain, we can help, whatever the surface.
Houses in smaller places like Lee-on-the-Solent can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
All our work comes with our 12-month guarantee, wherever you are in Hampshire.

Lee-on-the-Solent homes and the weather
Lee-on-the-Solent is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Osborne House (about 4.9 miles south-west) are a reminder that the area around Lee-on-the-Solent has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Fareham station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Lee-On-the-Solent Infant and Nursery School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Lee-on-the-Solent: your questions answered
I let a flat near Fareham station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is window mastic in a coastal place like Lee-on-the-Solent any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected.
How long will my window job take?
The work takes a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you do upstairs windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Why act early in Lee-on-the-Solent
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In an older home around Lee-on-the-Solent, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
When to call us in Lee-on-the-Solent
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Most people get in touch after spotting something like this:
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
- Draughts coming in around windows and doors
- Cracked or shrunken mastic around the frame
Homes close to Church of St Faith include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Whether VAT is included
- What insurance they hold
- Is the old sealant removed completely?
- When the joint can take water or movement
How to look after the new joints
Aftercare is simple:
- Keep paint off silicone joints
- Avoid harsh chemicals near the mastic
- Look round the frames every year or so
- Keep timber frames painted
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
