Commercial sealant around Alderholt
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as St James' Church of England First School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

Your questions about commercial sealant in Alderholt
Is commercial sealant in Alderholt guaranteed?
All our work, in Alderholt and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is Alderholt 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 you offer different sealant colours?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before we start.
Can you work around guests in a hotel?
Yes. We work through rooms in batches, keeping most rooms available. Each room comes back with its cure time for housekeeping.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Is out-of-hours working possible?
Often, yes. Let us know when the building is quietest, and we’ll plan the work around them.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes anything from a few hours to several days, depending on the number of rooms, depending on the size of the job. For a job in Alderholt, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We walk the site with you and agree the rooms, the order and the hours.
- Room by room, we protect the area and remove all the old sealant.
- Joints are cleaned, treated for mould and dried.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Each room is checked and handed back with its cure time.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions

DIY sealant or a professional job?
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Common problems we fix in Alderholt
Commercial buildings settle and move with temperature, and lightweight partitions flex more than masonry. The sealant between walls, trays and fittings absorbs that strain and eventually tear.
Signs it’s time to call us include:
- Failed floor-level joints in accessible wet rooms
- Whole floors of tired en suites
- Failed joints in office kitchens and tea points
- Joints that need doing before an inspection or audit
For buildings such as Church of St James, halls and community kitchens see heavy use, and their sealant shows it.

Why act early in Alderholt
Room by room, the work is quick: it takes a few hours per area, with larger sites planned over several visits. After that, each area needs its cure time before use, so the programme is planned around cure times. In a smaller place like Alderholt, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
