Window Mastic in Hammer Bottom
Window and door frames in Hammer Bottom need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

Window mastic in Hammer Bottom
Homes in Hammer Bottom have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We are often asked to deal with cold air getting in at the frame edge and untidy mastic left by window fitters, across patio & French doors, composite doors and uPVC windows.
Somewhere as small as Hammer Bottom, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.
What window mastic looks like in Hammer Bottom
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.
If you live in an older home near The Parish Church of St Peter, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Haslemere station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What affects the cost of window mastic
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- The type of sealant required
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
You do not need to know the technical terms. Just tell us:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Whether it has been sealed before
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
Common questions in Hammer Bottom
I let a flat near Haslemere station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you do window mastic in Hammer Bottom?
Yes. We work across London and the South East, and Hammer Bottom is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we’ll choose accordingly.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.

What else we do in Hammer Bottom
Why act early in Hammer Bottom
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Hammer Bottom can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Why us?
- Tidy, careful work
- You choose the colour before work begins
- Full insurance on every job
- Trusted Arbo and Everbuild sealants
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a handful of frames, longer for a whole house, depending on how much there is to do. In a small place like Hammer Bottom, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Clear the area around the work
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Advice
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we’re called out for in Hammer Bottom
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.
The most common problems we see are:
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Cold air getting in at the frame edge
- Black, perished sealant on frames
For site and facilities teams at buildings such as Woolmer Hill School, the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
