What affects the cost of window mastic
The price is agreed before any work begins. It’s based on:
- How many areas need sealing
- The product the joint needs
- The old material and how stubborn it is
- The number and length of the joints
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
To help us quote quickly, please include:
- A few photos by email, if you can
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- Where the property is
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Window mastic in Moorhouse Bank
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We are often asked to deal with rain getting in at the frame or under the sill and gaps left after new windows were fitted, across aluminium frames, window sills and composite doors.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Why it’s worth doing now in Moorhouse Bank
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Do you seal inside as well as outside?

Can you reach windows above the ground floor?

What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a few frames, or a day or more for a whole house. In Moorhouse Bank, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints

Landlord and commercial work in Moorhouse Bank
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Honest limits
It helps to know what we cannot do too:
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
- A sash or casement that won’t close properly
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on
- uPVC windows
- Composite doors
- Timber windows & doors
- Window sills
- Aluminium frames
- Patio & French doors
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Repaint timber before it’s bare
- Don’t use solvent cleaners on the joint
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.

Windows and doors in Moorhouse Bank
With historic houses such as Quebec House (about 1.3 miles east) nearby, there’s older building stock in the area around Moorhouse Bank as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
For an older house near a landmark such as St Andrew's, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Hurst Green 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.

Signs you need window mastic in Moorhouse Bank
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
The most common problems we see are:
- Gaps between the frame and the inside reveal
- Damp patches on the reveal after heavy rain
- Rushed sealant from a window installation
- Black, perished sealant on frames
If you look after a building such as Oxted School, its window and door frames need their mastic kept sound, just like a home’s.
