What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’ll tell you before we start. Sealant won’t put right:
- Faulty window hardware
- A door that needs adjusting, rehanging or new seals
- Damp coming through the wall itself rather than the frame joint

About our window mastic in Hazeley
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Typical jobs include leaking joints at the ends of sills and mastic that’s falling out in pieces, on window sills, timber windows & doors and aluminium frames.
In a village or hamlet like Hazeley, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You get a 12-month guarantee, the same in Hazeley as everywhere else we work.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes most of a day for a typical house, less for a few frames. Somewhere like Hazeley needs a little journey planning: 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 confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Why it’s worth doing now in Hazeley
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In a small place like Hazeley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Common questions in Hazeley
Can you help a landlord with a rental near Winchfield station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Hazeley within the area you cover?
Yes, Hazeley is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you have insurance?
Yes. We are fully insured.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
Is the work guaranteed?
Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What else we do in Hazeley
What we’re called out for in Hazeley
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
The most common problems we see are:
- Draughty joints inside around the window
- Draughts coming in around windows and doors
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
For landlords with property near Winchfield station, renewing tired window mastic between tenants heads off draught and damp complaints.

Window mastic in Hazeley: local notes
With historic houses such as Stratfield Saye House (about 3.1 miles north-west) nearby, there’s older building stock in the area around Hazeley as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Mattingley Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
