How we handle commercial sealant in Dartmouth Park
Mouldy or split sealant in a commercial building causes more than a bad impression. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. Common call-outs are for mouldy washroom sealant that staff and guests notice and large numbers of bathrooms needing the same work, across retail & leisure sites, rental portfolios and office washrooms & kitchens.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Dartmouth Park, and room-by-room programmes can be planned where needed.
You get a one-year guarantee, the same in Dartmouth Park as everywhere else we work.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What the job involves on each surface
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so joints are sealed with anti-fungal sanitary silicone.
Hotel bathrooms
We can plan around check-out and check-in times, with the order agreed with your team.
Questions from Dartmouth Park
Do you work for landlords with property near Gospel Oak station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you work for hotels and guest houses in Dartmouth Park?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Do you provide RAMS?
Let us know which documents your site needs, such as method statements, risk assessments or insurance details, and we will confirm what we can supply with the quote.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How to look after the new joints
So the new joints stay in good condition:
- Schedule work around occupancy
- Encourage users to squeegee shower walls
- Ask cleaners to go gently on the silicone
- Give housekeeping the cure time for every room
Squeegees in guest and staff showers help: less water sits on the joints between uses.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.

What happens on the day
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours per room, so whole buildings are phased from start to finish.

- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.

What we are called out for in Dartmouth Park
In office kitchens and tea points, joints are wet and wiped all day, so sealant there wears and stains. Worktop and sink joints are often the first to go.
Common reasons people contact us include:
- Split sealant where wet room floors meet walls
- Tired sealant in let properties
- Leaks from showers into rooms or ceilings below
- Whole floors of tired en suites
If you look after a building such as Acland Burghley School, busy washrooms and kitchens can be resealed in phases so they stay open.

Commercial buildings in Dartmouth Park
London’s water is hard, which leaves limescale on sealant, grout and taps. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
Community buildings like Church of St Mary Brookfield are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. As a London address, Dartmouth Park can be tricky for parking: let us know about parking bays, permits or a driveway.

What affects the cost of commercial sealant
Every job gets its own quote. These are the things that affect it:
- The size of the job
- Any working-time requirements on site
- Which sealant suits the joint
- Access and height
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the property is
- The problem you’ve noticed
- How we’d reach the joints
- How many joints, rooms or windows are involved
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work.
Why act early in Dartmouth Park
In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. Then two rooms are out of action, not one. A reseal now avoids that. In a flat in Dartmouth Park, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
