Commercial sealant for Letchworth Garden City homes and businesses
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Commercial sealant for homes and businesses in Letchworth Garden City
Commercial work is planned around the building, not the other way round. Rooms can be done one at a time, floor by floor or in batches, and out-of-hours work or early starts can be arranged. We work on student & care accommodation, welfare facilities and rental portfolios, and people most often call us about too many rooms to reseal without closing the building and repeated reseals that don’t last.
Washrooms in busy buildings wear their sealant out faster than a bathroom at home, while fire-rated sealant has to be made good whenever new pipes or cables go through. In Letchworth Garden City, timings are planned around the building.
Our work is backed for twelve months, in Letchworth Garden City and everywhere else we cover.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Give housekeeping the cure time for every room
- Don’t leave a failed joint until the next refurbishment
- Put a squeegee in each shower
- Use mild cleaners on sealant, not bleach or abrasives
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.
Letchworth Garden City questions
I let a flat near Letchworth Garden City station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
What guarantee comes with commercial sealant in Letchworth Garden City?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you start early or work out of hours?
In many cases. Tell us your opening hours and quiet times, and we’ll plan the work around them.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes as long as the scope needs, from one welfare room to a full building. In Letchworth Garden City, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start with a site walk to agree the rooms and the timing.
- Room by room, we protect the area and remove all the old sealant.
- The joints are degreased, treated and left to dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Replacing the sealant now is the simplest fix.
