Windows and doors in Stone Hill
Historic houses like Westenhanger Castle (about 2.2 miles south-east) are a reminder that the area around Stone Hill 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Sellindge Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Westenhanger station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

How we handle window mastic in Stone Hill
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on timber windows & doors, uPVC windows and patio & French doors, and common reasons people get in touch are hard, cracked sealant around windows and cracked internal joints between frame and plaster.
In a village or hamlet like Stone Hill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee.

What affects the quote in Stone Hill
Jobs vary more than people expect. The main factors:
- How much old sealant there is and how hard it is to remove
- Access and height
- Any working-time requirements on site
- The product the joint needs
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before we start.
Asking for a quote
Before you ask for a quote, have a think about:
- Photos by email, if that’s easy
- Where the job is, and your postcode
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes most of a day for a typical house, less for a few frames, depending on the amount of work. Somewhere as small as Stone Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

Advice
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep paint off silicone joints
- Ventilate rooms so frames do not stay wet inside
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

Is Stone Hill in your area for window mastic?
Yes, Stone Hill is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.

Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.
When is the sealant fully cured?
Cure times vary by product. Before we leave, we will tell you the cure time.
Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Work for landlords, hotels and businesses
For anyone letting property in or around Stone Hill, jobs at different addresses can go on one quote. Send us the addresses and the work at each.
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured for the work.
What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a small place like Stone Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

- A frame that has rotted at the joint
- Damp problems in the wall away from the window
