About our window mastic in Ruislip Manor
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 hard, cracked sealant around windows and rushed sealant from a window installation, on composite doors, timber windows & doors and patio & French doors.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Ruislip Manor as anywhere.
There’s a 12-month guarantee on every job.

Common questions in Ruislip Manor
Can parking be tricky for a visit in Ruislip Manor?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
I let a flat near West Ruislip station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What does window mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Do you guarantee window mastic?
Yes. Every job comes with our one-year guarantee, and we are ARBOMaster approved applicators.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

Ruislip Manor homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. With historic houses such as Ickenham Hall (about 1.5 miles south-west) nearby, there’s older building stock in the area around Ruislip Manor as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep jet washers away from the mastic
- Keep solvents and bleach off the sealant
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Why it’s worth doing now in Ruislip Manor
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Ruislip Manor, the repair is bigger than a sealant job.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- A choice of colours where the product allows
- A sealant colour to suit the surroundings
- Experience in homes, commercial sites and hotels
- Old sealant always removed completely

How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning for a couple of windows and a door. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Ruislip Manor. It helps if you can point us to a visitor permit or a bay close to the door.
- Each frame is looked over and we agree which ones need resealing.
- 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
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules

Advice
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- Whether the work is at height
- The type of sealant required
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Any previous sealing or DIY work
- A few pictures by email, if you can
- The problem you’ve noticed
- Where the property is
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or email us.
When to call us in Ruislip Manor
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Any of these means the joints need attention:
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
In the older streets around Church of St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What to look for in a quote
- Whether you can choose the colour
- Whether they’re fully insured
- Whether all the old sealant comes out first
- Whether VAT is included
