About our window mastic in Orchard Leigh
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on uPVC windows, timber windows & doors and patio & French doors, and common reasons people get in touch are black, perished sealant on frames and damp patches on the reveal after heavy rain.
Around Orchard Leigh, 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.
You get a 12-month guarantee, the same in Orchard Leigh as everywhere else we work.

How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Questions from Orchard Leigh
Is Orchard Leigh in your area for window mastic?
Yes. We work across London and the South East, and Orchard Leigh is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Orchard Leigh?
Yes. Orchard Leigh is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
What does window mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us with a short description of the job.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.
Can you do the inside joint as well?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Do you have sealant for grey or black windows?
Generally, yes. Tell us the frame colour when you get in touch and we will use the nearest match.
How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. Somewhere as small as Orchard Leigh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Advice
What affects the quote in Orchard Leigh
We quote each job individually. These are the things that affect it:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The size of the job
- Access and height
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Photos by email are helpful but not essential. Please mention:

When to call us in Orchard Leigh
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Any of these means the joints need attention:
- Draughty joints inside around the window
- Cold air getting in at the frame edge
- A bead that doesn’t match the frame
- Hard, cracked sealant around windows
Schools such as Ley Hill School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- How the colour is chosen
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- Which sealant they’ll use, and why

When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Damp coming through the wall itself rather than the frame joint
- A sash or casement that won’t close properly
- Rotten timber, which needs a joiner first
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

What window mastic looks like in Orchard Leigh
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Chenies Manor House (about 3.6 miles south-east) are a reminder that the area around Orchard Leigh 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.
In the older streets around St George's Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Berkhamsted 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.

How to look after the new joints
Aftercare is simple:
- Don’t aim a pressure washer at the joints
- Use gentle cleaners on frames and sealant
- Ventilate rooms so frames do not stay wet inside
- Make sure the drainage slots aren’t blocked
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
