Commercial sealant for homes and businesses in Andover
Office kitchens, staff washrooms and welfare facilities need to be usable every working day. We can plan the work for early mornings or out of hours so the working day is disturbed as little as possible. You’re told when each area can be used again. Common call-outs are for tired sealant in let properties and sealant failing again soon after quick repairs, across office washrooms & kitchens, hotel bathrooms and rental portfolios.
Washrooms in busy buildings wear their sealant out faster than a bathroom at home, and fire-rated joints need restoring whenever new services are run through a wall. For a building in Andover, we plan timings around how it’s used.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What we are called out for in Andover
A rushed reseal between guests rarely lasts. New silicone over old, joints that weren’t dried, or an unsuitable product all lead to the same thing: another reseal before long.
The most common problems we see are:
- Shower leaks reaching the floor below
- Whole floors of tired en suites
- Leaking joints in shower rooms and changing areas
- Rental bathrooms that need resealing between tenants
For buildings such as Church of St Mary, its kitchen and washroom sealant needs looking after like anywhere else.

Andover questions
Do you work for landlords with property near Andover station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do you take on hotel work around Andover?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
How long will you be here?
As a guide, most jobs take a few hours per area, with larger sites planned over several visits. Bigger jobs take longer, and we’ll tell you how long to expect.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Where are you based?
Mr Mastic is based in Crawley. We cover Andover and the rest of Hampshire.
What does commercial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
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 happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a morning for a small washroom, and a planned programme for bigger sites. For a job in Andover, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
Getting ready for the visit
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Advice
Commercial sealant in Andover: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. There are hotels and other places to stay in and around Andover. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
If you let a flat or house near Andover station, sealant work can be quoted for a single flat or a whole portfolio. Schools such as St John the Baptist Catholic Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Honest limits
New sealant can’t fix everything, and we will tell you before work begins. Sealant won’t put right:
- Cracked trays or baths rather than failed joints
- Tiles coming off the wall
- Fire risk assessments or certification
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Put a squeegee in each shower
- Note the date each area was done
- Tell cleaning staff when each room can be used
- Report broken fans quickly
Squeegees in guest and staff showers help: walls and trays dry faster, and so does the sealant.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
