Ellen's Green homes and the weather

How we handle window mastic in Ellen's Green
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on uPVC windows, aluminium frames and composite doors, and the jobs we see most are gaps between the frame and the inside reveal and cracked or shrunken mastic around the frame.
In a village or hamlet like Ellen's Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

What we’re called out for in Ellen's Green
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
People generally contact us when they notice something like this:
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
- White mastic on grey or black frames
- Gaps where the sill meets the wall
Rented homes near Warnham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why deal with it now?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Ellen's Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

How the job changes by surface
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- A frame that has rotted at the joint
- Draughts through the window seals rather than the frame
- Broken hinges, locks or handles
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.

FAQs for Ellen's Green
Can you help a landlord with a rental near Warnham station?

Do you cover smaller places like Ellen's Green?
Yes, Ellen's Green is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What do you put in the joint?
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.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.

Yes, with our one-year guarantee. A yearly look at the joints helps them last.
Do the sealants smell?

Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
What affects the cost of window mastic
You will get a clear quote before we start. It takes into account:
- The size of the job
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
To make quoting easier, let us know:
- How we’d reach the joints
- What’s wrong with the joints now
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or drop us an email.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
What happens on the day
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take most of a day for a typical house, less for a few frames. Somewhere like Ellen's Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Mention any parking rules near the property
