How we handle window mastic in Purbrook Heath
From a single sill to a whole house of windows, the work is priced before anything is done. Just phone 0345 464 0079 or email us and tell us how many frames there are and how they’re reached. If you are dealing with hard, cracked sealant around windows and cold air getting in at the frame edge, we can put it right, on uPVC windows, composite doors and patio & French doors alike.
Homes in small places like Purbrook Heath 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Windows and doors in Purbrook Heath
Purbrook Heath is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Warblington Castle (about 4.2 miles east) are a reminder that the area around Purbrook Heath 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.
Managing a site like Purbrook Junior School? Then larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of St John include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Purbrook Heath
Do you cover smaller places like Purbrook Heath?
Yes, Purbrook Heath is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Cosham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you have sealant for grey or black windows?
Yes, in most cases. Tell us the frame colour when you get in touch and we will use the nearest match.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Where are you based?
Mr Mastic is based in Crawley. We cover Purbrook Heath and the rest of Hampshire, along with the rest of our area.
How the job changes by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In a small place like Purbrook Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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. All the old material has to come out first.
Common problems we fix in Purbrook Heath
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Look out for any of the following:
- Untidy mastic left by window fitters
- White mastic on grey or black frames
- Draughty joints inside around the window
- Whistling draughts around closed windows
For landlords with property near Cosham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It generally takes anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Purbrook Heath, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.

How to look after the new joints
Looking after new joints is easy:
- Do not use solvent cleaners on the joint
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
- Avoid blasting the frames with a pressure washer
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
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. If you notice one, it’s time to get the joint looked at.
