Window mastic for homes and businesses in Strood Green
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on aluminium frames, patio & French doors and timber windows & doors, and the jobs we see most are untidy mastic left by window fitters and sealant in the wrong colour for the frame.
Mastic can only go onto a dry, clean joint, so window work in Strood Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Do you need window mastic in Strood Green?
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Keep an eye out for these signs:
- Hard, cracked sealant around windows
- Draughts coming in around windows and doors
- Rushed sealant from a window installation
- White mastic on grey or black frames
Schools such as North Downs Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What else we do in Strood Green
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Strood Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.

FAQs for Strood Green
I let a flat near Betchworth station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Will you come out to Strood Green?
Yes, Strood Green is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
How long before the joint can be used?
It depends on the product. Before we leave, we will tell you the cure time.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Strood Green.
The process
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work usually takes a morning for a couple of windows and a door. For a village or hamlet like Strood Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- 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.
Getting ready for the visit
- Mention any tricky access
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What window mastic looks like in Strood Green
Historic houses like Polesden Lacey (about 4.6 miles north-west) are a reminder that the area around Strood Green 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Christ Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Betchworth station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
