- Gaps left after new windows were fitted
- Cracked sealant at the sill ends
How we handle window mastic in Butlocks Heath
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We are often asked to deal with cracked internal joints between frame and plaster and old mastic that has gone black or come away, on composite doors, aluminium frames and window sills.
Mastic can only go onto a dry, clean joint, so window work in Butlocks Heath is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

What we are called out for in Butlocks Heath
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- Draughty joints inside around the window
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
Homes close to Church of St Mary include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Quotes for window mastic in Butlocks Heath
Your quote is based on your job. We look at:
- Access and height
- Which sealant suits the joint
- The number of rooms or windows
- Whether there’s mould to deal with
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
- A few pictures by email, if you can
- Whether it’s a home or a business
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- A door that needs adjusting, rehanging or new seals
- Broken hinges, locks or handles
- Soft or decayed wood in the frame
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Questions from Butlocks Heath
Is Butlocks Heath within the area you cover?
Yes. Butlocks Heath is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is window mastic in a coastal place like Butlocks Heath any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can new window sealant be painted?
Not generally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Windows and doors in Butlocks Heath
Butlocks Heath is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Medieval Merchant's House (about 3.2 miles north-west) are a reminder that the area around Butlocks Heath has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Netley Abbey Infant School? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Netley station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why it’s worth doing now in Butlocks Heath
The work is quick compared with the damage it prevents: 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. Where a wall is exposed, as many are in small places like Butlocks Heath, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

What else we do in Butlocks Heath
The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a morning for a couple of windows and a door, depending on how much there is to do. Somewhere as small as Butlocks Heath, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Preparing for the visit
- Clear the area around the work
- On commercial sites, let us know about site rules
