Portmore: your questions answered
Do you take on hotel work around Portmore?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Will you come out to Portmore?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is the work guaranteed?
Yes. Every job comes with a 12-month guarantee.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do you provide RAMS?
We are fully insured, so start by telling us what your site asks for. Send over your requirements and we will confirm what we can provide.
How long does commercial sealant take?
A typical job takes as long as the scope needs, from one welfare room to a full building. Your quote will say how long we expect yours to take.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Commercial sealant for homes and businesses in Portmore
Landlords and agents with several properties can have bathrooms and kitchens resealed between tenancies. Several addresses can be quoted together to keep things simple. We work on welfare facilities, office washrooms & kitchens and student & care accommodation, and common reasons people get in touch are silicone laid over old silicone by a previous contractor and rental bathrooms that need resealing between tenants.
In a village or hamlet like Portmore, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Our work is backed for twelve months.

Why act early in Portmore
Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, with less disruption and one clear quote. Around Portmore, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of rooms. For a village or hamlet like Portmore, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
How to prepare
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
Getting a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or email us.

Commercial sealant in Portmore: local notes
If you run a hotel, guest house or holiday let in a coastal place like Portmore, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. There are hotels and other places to stay in and around Portmore. Hotel work can be planned room by room, with out-of-hours working where needed.
For site and facilities teams at buildings such as Southlands School, washroom and kitchen sealant can be programmed around term times or opening hours. Letting a property close to Lymington Town station? Then sealant work can be quoted for a single flat or a whole portfolio. Community buildings like Saint Nicholas Chapel are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Act on lifting sealant before it leaks
- Encourage users to squeegee shower walls
- Ask cleaners to go gently on the silicone
- Check the joints during routine room inspections
Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix.
Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Dealing with the joint early stops that spread.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
