Window mastic in North Warnborough
Around North Warnborough we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Typical jobs include gaps where the sill meets the wall and old mastic that has gone black or come away, across aluminium frames, timber windows & doors and window sills.
Around North Warnborough, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Every job comes with our one-year guarantee.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Wash the frames with mild soapy water
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
FAQs for North Warnborough
I let a flat near Hook station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Can you do window mastic in North Warnborough?
Yes, North Warnborough is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can I paint over the new sealant?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.
What affects the quote in North Warnborough
The price is agreed before any work begins. It takes into account:
- Whether the work is at height
- When we can work, for business premises
- Any mould that needs treating
- How many areas need sealing
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Helping us quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
Every job is quoted individually. Just ring 0345 464 0079 or drop us an email with the details and send photos if you have them.
Windows and doors in North Warnborough
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Hook station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Robert May's School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to All Saints Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Why it’s worth doing now in North Warnborough
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a small place like North Warnborough, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Advice
When something else is needed
Before booking, it’s worth knowing the limits too:
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.
