When to call us in Stanway
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The most common problems we see are:
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Sealant in the wrong colour for the frame
- Cold air getting in at the frame edge
If you look after a building such as Stanway Primary School, its window and door frames need their mastic kept sound, just like a home’s.

How we handle window mastic in Stanway
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include cold air getting in at the frame edge and leaking joints at the ends of sills, on timber windows & doors, uPVC windows and composite doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stanway is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by our 12-month guarantee.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Leave it or put it right?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Older cottages and farmhouses around Stanway can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.
Why book with us
- You choose the colour before work begins
- Over 20 years’ experience
- Experience in homes, commercial sites and hotels
- Approved under the ARBOMaster scheme

Stanway questions
Do you work for landlords with property near Marks Tey station?
Yes. We work for letting agents and landlords as well as householders. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Stanway?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
Looking after it afterwards
So the new joints stay in good condition:
- Air rooms to keep condensation down around windows
- Don’t paint over the silicone
- Don’t use solvent cleaners on the joint
- Make sure the drainage slots aren’t blocked
Most silicone sealants won’t take paint, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What we do, step by step
The work is kept neat and contained to the joints we are treating. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we explain the cure time before we leave. For a village or hamlet like Stanway, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Before we arrive
- Move anything stored near the joints
- Mention any tricky access
- Mention if the joints have been sealed before

What window mastic looks like in Stanway
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Layer Marney Tower (about 4.2 miles south) are a reminder that the area around Stanway 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.
Homes close to Parish Church of St Albright include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Marks Tey station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
