What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. We use a neutral-cure product.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
How we handle window mastic in Little Almshoe
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, ring 0345 464 0079 or send us an email with the number of frames and any access details. We work on timber windows & doors, window sills and patio & French doors, and common reasons people get in touch are rain getting in at the frame or under the sill and gaps where the sill meets the wall.
In a village or hamlet like Little Almshoe, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Little Almshoe: your questions answered
Do you cover smaller places like Little Almshoe?
Yes. Little Almshoe 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.
Is Little Almshoe in your area for window mastic?
Yes, Little Almshoe is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Can you do upstairs windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Do you have insurance?
Yes. We are fully insured.
Is the work guaranteed?
Yes, for 12 months. A yearly look at the joints helps them last.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before work begins.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Can you do the inside joint as well?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Clear any debris from frame drain holes
- Use gentle cleaners on frames and sealant
- Wipe condensation off the frames
- Keep jet washers away from the mastic
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
When it isn’t the sealant
New sealant can’t fix everything, and we will tell you before work begins. It will not solve:
- Condensation trapped between the panes
- A sash or casement that won’t close properly
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

What window mastic looks like in Little Almshoe
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Knebworth House (about 3.8 miles south-east) are a reminder that the area around Little Almshoe has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Ippolyts (church of England) 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 Hitchin station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like St Ippolyts Church of England Aided Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Quotes for window mastic in Little Almshoe
Jobs vary more than people expect. The main factors:
- Whether there’s mould to deal with

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a few frames, or a day or more for a whole house. In a small place like Little Almshoe, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
