Window mastic in Green Street, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. Typical jobs include cold air getting in at the frame edge and cracked or shrunken mastic around the frame, on aluminium frames, patio & French doors and uPVC windows.
Around Green Street, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What affects the quote in Green Street
Your quote is based on your job. We look at:
- Any mould that needs treating
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- Where the property is
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
FAQs for Green Street
Does living near the coast affect window mastic in Green Street?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
I let a flat near Crowhurst station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
Is the new sealant paintable?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Where are you based?
We work from Crawley. We cover Green Street and the rest of East Sussex, along with the rest of our area.
Do you cover Green Street?
Yes. We cover Green Street, as part of our work across South East England, London and Scotland. To book, ring 0345 464 0079 or send us an email.

Why act early in Green Street
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Green Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.

Green Street homes and the weather
Green Street is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Crowhurst CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Crowhurst station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near The Parish Church of St George, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Wash the frames with mild soapy water
- Paint up to the joint, not over it
- Air rooms to keep condensation down around windows
- Clear any debris from frame drain holes
Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
The process
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Green Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
