How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Bow Common. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions

Advice
Window mastic for homes and businesses in Bow Common
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Typical jobs include mastic that’s falling out in pieces and rain getting in at the frame or under the sill, 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. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.

Common problems we fix in Bow Common
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. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for these signs:
- Damp patches on the reveal after heavy rain
- Draughts coming in around windows and doors
- Sealant in the wrong colour for the frame
- Untidy mastic left by window fitters
Historic houses such as Sutton House, about 2.4 miles north-west, show how far back building around Bow Common goes.

Looking after it afterwards
So the new joints stay in good condition:
- Do not use solvent cleaners on the joint
- Wash the frames with mild soapy water
- Avoid blasting the frames with a pressure washer
- Make sure the drainage slots aren’t blocked
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

Common questions in Bow Common
Is parking a problem for a job in Bow Common?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you cover Bow Common for window mastic?
Yes, Bow Common is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you have insurance?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Do you seal inside as well as outside?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Faulty window hardware
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Timber windows & doors
- Aluminium frames
- Patio & French doors
- uPVC windows
- Composite doors
- Window sills
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Frames and glazing around Bow Common
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. With historic houses such as Sutton House (about 2.4 miles north-west) nearby, there’s older building stock in the area around Bow Common as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
As a London address, Bow Common can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as St Paul's Way Trust School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
