Bowmans Window Mastic
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Bowmans. Fully insured, ARBOMaster approved and guaranteed for a year.
- Draughty joints inside around the window
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like Bowmans, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

Advice
About our window mastic in Bowmans
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have draughty joints inside around the window and a bead that doesn’t match the frame, we can help, on uPVC windows, timber windows & doors and aluminium frames alike.
In a smaller place like Bowmans, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Questions from Bowmans
I let a flat near Crayford station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is Bowmans in your area for window mastic?
Yes. Our work covers London and the South East, and Bowmans is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long before the joint can be used?
It depends on the product. Before we leave, we will tell you the cure time.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Use gentle cleaners on frames and sealant
- Wipe condensation off the frames
- Do not use solvent cleaners on the joint
- Check the mastic once a year
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

What to tell us for a quote

Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved and give you a clear price.
Signs you need window mastic in Bowmans
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
People generally contact us when they notice one of these:
- Rushed sealant from a window installation
- Mastic that has split away from the wall
- Draughty joints inside around the window
- Draughts coming in around windows and doors
In the older streets around St Barnabas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Frames and glazing around Bowmans
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hall Place and Gardens (about 1.1 miles north-west) are a reminder that the area around Bowmans has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Wentworth Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Crayford station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
