Frames and glazing around East Stratton
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.
For an older house near a landmark such as Church of All Saints, the joint between an old wall and a newer frame is normally the first place rain gets in.
East Stratton is about 8 miles north-east of Winchester, in Hampshire. Across the SO21 area, we can carry out sand mastic at your property. East Stratton is one of 683 towns and villages in Hampshire we cover. We also work in Southampton, around 18 miles away.

Sand mastic in East Stratton
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We work on timber door frames, sash and case windows and stone surrounds, and people most often call us about tired mastic found when preparing windows for paint and draughts and rain around sash boxes.
In a village or hamlet like East Stratton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
You get a one-year guarantee, the same in East Stratton as everywhere else we work.

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours per window, depending on the condition of the joints, including the tidy-up. In a small place like East Stratton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children

How we quote for sand mastic
Every job gets its own quote. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- Access and height
- Working hours on commercial sites
- How many rooms, windows or areas are involved
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- The rough size of the job
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Landlord and commercial work in East Stratton
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We also work for property managers and facilities teams in East Stratton and across Hampshire. We can quote a run of properties together.
Why deal with it now?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In a small place like East Stratton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

East Stratton: your questions answered
Can you help a landlord with a rental near Micheldever station?
Yes. We work for landlords and agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Is East Stratton within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long does sand mastic take?
A typical job takes a few hours for a single window, longer for several, including preparation and clearing up. We will confirm how long when we quote.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
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.
How the job changes by surface
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep modern sealant off the mastic
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
- Get any rot dealt with first
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
What we’re called out for in East Stratton
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Signs it’s time to call us include:
- Weathered mastic on the most exposed windows
- Gaps where the frame meets the masonry
- Mastic dropping out of the joint
- Wind and rain getting in round a sash window
Rented homes near Micheldever station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
