Much Hadham questions
Is Much Hadham in your area for commercial sealant?
Yes, Much Hadham is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near Bishops Stortford station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you guarantee commercial jobs?
Yes, with our 12-month guarantee. Mild cleaning and good ventilation help it last.
Is out-of-hours working possible?
In many cases. Tell us your opening hours and quiet times, and we will see what can be arranged.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can you take on a whole building?
Yes. We work through big sites room by room or floor by floor, keeping most of it in use.
Keeping the joints in good condition
So the new joints stay in good condition:
- Ask cleaners to go gently on the silicone
- Encourage users to squeegee shower walls
- Pass on the cure time to whoever cleans the rooms
- Get split or lifting joints looked at early
Each room is handed back with its cure time, usually around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, so the fix is replacement.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
When something else is needed
A few problems are outside what sealant work can do:
- Failed tanking or loose tiles behind the sealant
- Faulty shower valves and leaking traps
- Poor ventilation that keeps bringing mould back
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Rental portfolios
- Student & care accommodation
- Retail & leisure sites
- Welfare facilities
- Hotel bathrooms
- Office washrooms & kitchens
What happens if it’s left?
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. Resealing first is the smaller job. In a small place like Much Hadham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

When to call us in Much Hadham
Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading. A tray that isn’t fully supported soon tears its seal.
Most people get in touch after spotting something like this:
- Tired sealant ahead of a health and safety audit
- Repeated reseals that do not last
- Failed floor-level joints in accessible wet rooms
- Tired sealant in let properties
If you look after a church, hall or community building such as Parish Church of St Andrew, its kitchen and washroom sealant needs looking after like anywhere else.

What happens on the day
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work normally takes a morning for a small washroom, and a planned programme for bigger sites. Somewhere as small as Much Hadham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We let your team know the cure time for every area.
Preparing for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
