How we quote for commercial sealant
There’s no set price list. The quote depends on:
- The number and length of the joints
- Mould in or behind the old joints
- Any working-time requirements on site
- The type of sealant required
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it has been sealed before
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
We do not publish a price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.
Commercial sealant in Blackwater
Larger jobs around Blackwater start with a walk round the site. You then get one clear quote for the whole job. To set one up, phone 0345 464 0079 or drop us an email. We work on welfare facilities, rental portfolios and office washrooms & kitchens, and the jobs we see most are split sealant where wet room floors meet walls and silicone laid over old silicone by a previous contractor.
In a village or hamlet like Blackwater, 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.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Signs you need commercial sealant in Blackwater
Plenty of commercial bathrooms have no window at all, and where extraction is poor, damp hangs around. That’s when black mould sets into the bead.
Keep an eye out for any of the following:
- Tired sealant ahead of a health and safety audit
- Failed joints in office kitchens and tea points
- Black, stained silicone in guest bathrooms
- Whole floors of tired en suites
Schools such as Christ The King College are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours.
What to look for in a quote
- What product goes in the joint
- Whether they seal over old material or remove it
- What happens if the job turns out different
- How the surfaces are prepared before sealing
What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours per area, with larger sites planned over several visits. Somewhere as small as Blackwater, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- We clean the joints, treat any mould and let them dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Rooms are checked and returned with a cure time so staff know when to use them.
Preparing for the visit
- Mention any parking rules near the property
- Clear items away from the joints we are working on
- Keep children and pets away from the work area

Related advice
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Leave it or put it right?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. Around Blackwater, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Community buildings like St. Olave's Church are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.
