About our window mastic in Bury Green
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Common call-outs are for gaps where the sill meets the wall and untidy mastic left by window fitters, across timber windows & doors, patio & French doors and window sills.
Mastic can only go onto a dry, clean joint, so window work in Bury Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Why it’s worth doing now in Bury Green
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Bury Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Bury Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints

Advice
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you are 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.
FAQs for Bury Green
Can you do window mastic in Bury Green?
Yes. Our work covers London and the South East, and Bury Green is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near Bishops Stortford station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you match the sealant to my frames?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Penetrating damp from a failed cavity tray or render
- Condensation trapped between the panes
- A door that needs adjusting, rehanging or new seals
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Window sills
- uPVC windows
- Aluminium frames

Frames and glazing around Bury Green
With historic houses such as Much Hadham Palace (about 1.5 miles south-west) nearby, there’s older building stock in the area around Bury Green 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Bishops Stortford station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Parish Church of St Cecilia, the joint between an old wall and a newer frame is usually the first place rain gets in.

Do you need window mastic in Bury Green?
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Cold air getting in at the frame edge
- Gaps left after new windows were fitted
- A bead that doesn’t match the frame
- Cracked sealant at the sill ends
Managing a site like Little Hadham Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
