What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes as long as the scope needs, from one welfare room to a full building. Somewhere as small as Heronsgate, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Preparing for the visit
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

FAQs for Heronsgate
Is Heronsgate within the area you cover?
Yes. Heronsgate is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Chorleywood station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Can you work around guests in a hotel?
Usually, yes. We agree the room order and times with your managers, and you’ll know when each room can be used.
Is out-of-hours working possible?
Out-of-hours work and early starts can be arranged. Tell us what you need when you ask for a quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can you take on a whole building?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, so only part of the building is affected at once.

Customer washrooms are part of the impression a business makes, and fresh sealant makes them look well kept.

Quotes for commercial sealant in Heronsgate
Some jobs are bigger than they look, and some smaller. The main factors:
- Working hours on commercial sites
- Whether there’s mould to deal with
- The old material and how stubborn it is
- Whether the work is at height
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
- The type of property
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or send us an email.
Landlords, agents and businesses in Heronsgate
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Water damage behind the tiles that needs a tiler or builder
- A broken extractor fan behind the mould problem
- A shower tray, bath or basin that is cracked or broken
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Workplaces and buildings in Heronsgate
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.
For buildings such as St John, any kitchen and washrooms need the same sealant care as any other building. For site and facilities teams at buildings such as Chorleywood Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

When to call us in Heronsgate

The problems people normally mention when they call are:
- Black, stained silicone in guest bathrooms
- Tired sealant in let properties
- Large numbers of bathrooms needing the same work
- Tired sealant ahead of a health and safety audit
If you let a flat or house near Chorleywood station, several rental properties can be resealed on one programme.
Before you book anyone

- The length of the guarantee
- Whether they’re fully insured
- How the joint is cleaned and prepared
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
