Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
How we handle sand mastic in Fishbourne
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We’re often asked to deal with window mastic to renew ahead of painting and gaps where the frame meets the masonry, on timber door frames, stone surrounds and tenement windows.
Mastic can only go onto a dry, clean joint, so window work in Fishbourne is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, large or small.

Windows and doors in Fishbourne
Fishbourne is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
In the older streets around St. Edmund's Church, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Ryde Esplanade station, any sash windows need sound mastic to keep draughts and rain out.
Fishbourne is about 2 miles west of Ryde, in the Isle of Wight. Jobs in Fishbourne get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Across the Isle of Wight, we cover 125 places, Fishbourne among them. Portsmouth is on our list too, about 8 miles from Fishbourne.
Every address in PO33 is covered for sand mastic. Local streets include Kite Hill, Ashlake Farm Lane and Ashlake Copse Road, and we cover them all. Fishbourne sits on or near the B3331, which makes travel easy. We also cover Wootton (1 mile west), Havenstreet (1 mile south), Hillgrove (2 miles south-west), Whippingham (2 miles west) and Staplers (3 miles south-west). Within a short drive, we also cover Newport (4 miles south-west), Cowes (4 miles north-west), Sandown (6 miles south-east), Shanklin (7 miles south), Ventnor (9 miles south) and East Cowes (3 miles north-west). For island and remote addresses, the job takes a little more planning, so let us know when you get in touch.

What affects the cost of sand mastic
Every job gets its own quote. This is what makes a difference:
- How easy the joints are to reach
- The number of rooms or windows
- The number and length of the joints
- Any mould that needs treating
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.
Asking for a quote
When you contact us, these details help:
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Photos by email, if that is easy
Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or email us with the details, and pictures are welcome.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Find out about consent before window work on a listed home
- Look over the window mastic once a year
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Why act early in Fishbourne
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new work lasts. In a small place like Fishbourne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Signs you need sand mastic in Fishbourne
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
People normally contact us after spotting one of these:
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
- Draughty sash windows at the surround
For site and facilities teams at buildings such as Wootton Community Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Are they insured?
- How long the guarantee is
- Whether VAT is included
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Cracked or broken glass
- Sash cords, weights and draught-proofing of the sashes
- Whether work needs listed building consent
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Questions from Fishbourne
Will you come out to Fishbourne?
Yes. Fishbourne is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does living near the coast affect sand mastic in Fishbourne?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic generally suits period timber windows best. Modern frames normally suit a flexible sealant.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What does sand mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Fishbourne, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about parking restrictions
- Mention any tricky access
