Your questions about window mastic in Hassell Street
Is Hassell Street in your area for window mastic?

Is Hassell Street within the area you cover?
Yes. Hassell Street 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.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Can resealing stop a draught around my window?
Often, yes. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Can I paint over the new sealant?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

Yes. Our one-year guarantee covers every job.
Where do you work from?

How we handle window mastic in Hassell Street
Around Hassell Street we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Common call-outs are for hard, cracked sealant around windows and damp patches on the reveal after heavy rain, across composite doors, window sills and uPVC windows.
In a village or hamlet like Hassell Street, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What else we do in Hassell Street
Do you need window mastic in Hassell Street?
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
The most common problems we see are:
- White mastic on grey or black frames
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
- Cold air getting in at the frame edge
Schools such as Wye School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How we quote for window mastic
Call for a quick quote. The main things that affect it are:
- The product the joint needs
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Whether the work is at height
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- How we’d reach the joints
- The rough size of the job
- Whether it has been sealed before
- Whether it’s a home or a business
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. For a village or hamlet like Hassell Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work

Advice
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
