Frames and glazing around The Willows
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Stansted Mountfitchet station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
The Willows is about 5 miles north-west of Bishop's Stortford, in Hertfordshire. From the centre of The Willows to the outskirts, window mastic is available for homes and businesses alike, from flats and houses to offices and hotels.

All of SG9 is covered for window mastic, from the main roads to the quietest streets.

How we handle window mastic in The Willows
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on aluminium frames, patio & French doors and uPVC windows, and people most often call us about water coming in at the bottom corners of a door and hard, cracked sealant around windows.
Homes in small places like The Willows often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Our work is backed for twelve months, in The Willows and everywhere else we cover.

Your questions about window mastic in The Willows
Is The Willows within the area you cover?
Yes. The Willows is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Stansted Mountfitchet station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
How do I get a quote for window mastic in The Willows?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Do you seal inside as well as outside?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we’re ARBOMaster approved applicators.
What we’re called out for in The Willows
Water runs down the glass onto the sill, 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.
The most common problems we see are:
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- White mastic on grey or black frames
Schools such as Furneux Pelham Church of England School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- What product goes in the joint
- What the cure time is
- Which colour the sealant will be
- Who does the work, and how experienced they are
What sealant work cannot fix
We will always be straight with you, so here’s what new sealant will not do:
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Faulty window hardware
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Timber windows & doors
- Window sills
- Composite doors
- uPVC windows
- Aluminium frames
- Patio & French doors
Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a small place like The Willows, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
- Keep paint off silicone joints
- Ventilate rooms so frames don’t stay wet inside
Try not to touch the new joint while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What we do, step by step
The work is kept neat and contained to the joints we’re treating. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. In a small place like The Willows, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Surface by surface
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it, where a rigid one would crack.
