What happens on the day
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in.

If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Advice
Commercial sealant for homes and businesses in High Cross
In a hotel, office or washroom, failed sealant is more than an eyesore. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We are often asked to deal with tired sealant ahead of a health and safety audit and worktop sealant that has shrunk and stained, on office washrooms & kitchens, rental portfolios and hotel bathrooms.
Somewhere as small as High Cross, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we cannot put right
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Extraction that isn’t working, which needs an electrician or ventilation contractor
- Fire risk assessments or certification
- Tiles coming off the wall
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Rental portfolios
- Retail & leisure sites
- Welfare facilities
- Hotel bathrooms
- Student & care accommodation
- Office washrooms & kitchens
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Add sealant to your planned maintenance checks
- Schedule work around occupancy
- Use mild cleaners on sealant, not bleach or abrasives
- Note the date each area was done
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
Black sealant in a staff washroom or guest bathroom draws complaints. The longer it’s left, the deeper it grows into the silicone, and only replacement fixes it.
Leave it or put it right?
Before an inspection, audit or busy season, sealant is easy to overlook. Planning the work ahead means rooms are finished and cured in time. Older cottages and farmhouses around High Cross can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.

Community buildings like Church of St John the Evangelist are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. Rented homes near Ware station change hands often, and several rental properties can be resealed on one programme.

FAQs for High Cross
Can you help a landlord with a rental near Ware station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is High Cross within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you provide RAMS?
Tell us what paperwork your site needs, such as method statements, risk assessments or insurance details, and we will confirm what we can provide when we quote.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you work around guests in a hotel?
Yes. Rooms are done a few at a time, keeping most rooms available. Housekeeping are told when each room can be let again.
Do you need commercial sealant in High Cross?
Staff kitchens and food areas see constant splashing and wiping, and grease and cleaning sprays break down sealant. The worktop and sink edges normally fail first.
People normally contact us when they notice something like this:
- Shower leaks reaching the floor below
- Joints that need doing before an inspection or audit
- Washroom sealant that looks dirty however often it’s cleaned
- Tired sealant in let properties
For site and facilities teams at buildings such as Thundridge Church of England Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
