About our commercial sealant in Highmoor
Landlords and agents with several properties can have bathrooms and kitchens resealed between tenancies. Several addresses can go on one quote to keep things simple. If you’re dealing with split sealant around staff kitchen worktops and sinks and washroom sealant that looks dirty however often it’s cleaned, we can put it right, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near Highmoor, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Questions from Highmoor
Do you work in hotels near Highmoor?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you cover smaller places like Highmoor?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How much does commercial sealant cost in Highmoor?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email and let us know what needs doing and where.
When can guests or staff use the shower again?
Around 24 hours is typical for sanitary silicone. Housekeeping get the cure time for each room.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
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.
When to call us in Highmoor
Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading all work at the joint. A tray that is not fully supported soon tears its seal.
The most common problems we see are:
- Mouldy washroom sealant that staff and guests notice
- Split sealant around staff kitchen worktops and sinks
- Repeated reseals that don’t last
- Leaks from showers into rooms or ceilings below
Community buildings like Church of St Paul are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.
Questions to ask before booking
- What the quote includes, VAT included or not
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
- Who turns up on the day
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. For a village or hamlet like Highmoor, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

When something else is needed
To be straight with you, some problems need a different trade:
- Certifying fire stopping or building compliance
- Damaged sanitaryware that needs replacing
- Extraction that isn’t working, which needs an electrician or ventilation contractor
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.
Surfaces we seal
- Welfare facilities
- Hotel bathrooms
- Retail & leisure sites
- Office washrooms & kitchens
- Rental portfolios
- Student & care accommodation
Leave it or put it right?
Fixing rooms one complaint at a time is the slow way. A planned programme deals with every room in order, with less disruption and one clear quote. In a small place like Highmoor, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

Commercial sealant in Highmoor: local notes
There are hotels and other places to stay in and around Highmoor. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a building such as Stoke Row Church of England School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Rented homes near Henley-On-Thames station change hands often, and several rental properties can be resealed on one programme.

How we quote for commercial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many rooms, windows or areas are involved
- Which sealant suits the joint
- Mould in or behind the old joints
- The number and length of the joints
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- A few pictures by email, if you can
- The address or postcode of the job
- Whether it has been sealed before
- The type of property
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 explain what’s involved and give you a clear quote.
Looking after it afterwards
After the cure time, these simple habits help:
- Give housekeeping the cure time for every room
- Act on lifting sealant before it leaks
- Check the joints during routine room inspections
- Keep extractor fans working and serviced
We give a cure time for every area we finish, which is normally around 24 hours. Make sure housekeeping or cleaning staff know it so the new sealant is not wetted or scrubbed too soon.
It’s easier to plan a programme than to react to failures. Rooms can be scheduled around occupancy and staff, rather than closed at short notice.
