Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Window mastic in Knights Enham, done properly
Homes in Knights Enham have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Typical jobs include sealant in the wrong colour for the frame and cold air getting in at the frame edge, across window sills, composite doors and patio & French doors.
Somewhere as small as Knights Enham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Knights Enham: your questions answered
Do you cover smaller places like Knights Enham?
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 do window mastic in Knights Enham?
Yes, Knights Enham is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
How long does it take to reseal the windows on a house?
The work takes a few hours for a handful of frames, longer for a whole house. Access and how stubborn the old mastic is affect the time most.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is the new sealant paintable?
Not usually, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is it OK to seal over old sealant?
No. The old sealant always comes out first.
Knights Enham homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Andover station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to Church of St Michael and All Angels include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Advice
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Different surfaces, different methods
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Common problems we fix in Knights Enham
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- Untidy mastic left by window fitters
- Black, perished sealant on frames
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
For site and facilities teams at buildings such as Roman Way Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- Whether they seal over old material or remove it
- Whether they’re fully insured
- Whether you can choose the colour
- How long to leave it before use
What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- The product the joint needs
- How many areas need sealing
- Whether the work is at height
- Mould in or behind the old joints
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Where the property is
- Roughly how big the job is
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.
What sealant work can’t fix
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.
