How we handle commercial sealant in Blackwater
For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. We can quote for several properties at once to keep things simple. If you’re dealing with shower leaks reaching the floor below and leaking joints in shower rooms and changing areas, we can put it right, whatever the surface.
If you run a pub, café, guest house or shop in or near Blackwater, its washrooms and kitchen need the same sealant care as any big building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Leave squeegees in busy showers
- Book larger programmes for quieter times of year
- Tell cleaning staff when each room can be used
- Keep a record of which rooms were resealed and when
Squeegees in guest and staff showers help: less water sits on the joints between uses.
Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.
What affects the quote in Blackwater
Every job gets its own quote. These are the things that affect it:
- How many areas need sealing
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The type of sealant required
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What to tell us for a quote
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- Whether it’s a home or a business
- How we’d reach the joints
For a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before work begins.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Water damage behind the tiles that needs a tiler or builder
- A broken extractor fan behind the mould problem
- Damaged sanitaryware that needs replacing
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

Leave it or put it right?
Sealant work is quick by the room: the job takes anything from a few hours to several days, depending on the number of rooms. Each area is then left to cure for the time we give you, so planning the order matters more than the hours on site. In a smaller place like Blackwater, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours per area, with larger sites planned over several visits. A visit to Blackwater is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We agree a programme with you: which rooms, in what order, at what times.
- Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
