Commercial sealant around Wildhern
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For landlords with property near Andover station, several rental properties can be resealed on one programme. Schools such as Hatherden Church of England Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

What we’re called out for in Wildhern
Internal washrooms and en suites without a window rely entirely on extraction, so if the fan is weak, steam lingers and the sealant stays damp. Mould then takes hold in the silicone.
Common reasons people contact us are:
- Silicone laid over old silicone by a previous contractor
- Split sealant around staff kitchen worktops and sinks
- Joints that need doing before an inspection or audit
- Leaking joints in shower rooms and changing areas
For buildings such as Christchurch, halls and community kitchens see heavy use, and their sealant shows it.
Questions to ask before you book
- How long to leave it before use
- How the surfaces are prepared before sealing
- Whether they seal over old material or remove it
- The length of the guarantee
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Why it’s worth doing now in Wildhern
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. Where a wall is exposed, as many are in small places like Wildhern, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours for a single washroom, longer for a whole building. Somewhere as small as Wildhern, access is often the only tricky part. 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.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Clear the area around the work

Different surfaces, different methods
Rental portfolios
Good sealant prevents leaks that cause bigger repairs, especially where you rarely see the bathroom yourself.
Office washrooms & kitchens
In staff kitchens, we degrease joints before resealing, using a food-safe sealant by sinks where it’s needed.
Common questions in Wildhern
Can you help a landlord with a rental near Andover station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Wildhern in your area for commercial sealant?
Yes, Wildhern is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Can you match the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Can you start early or work out of hours?
Often, yes. Let us know when the building is quietest, and we’ll plan the work around them.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Does commercial work come with a guarantee?
Yes. We are fully insured, ARBOMaster approved and give a one-year guarantee on every job.
How long does commercial sealant take?
Typically it takes a few hours per room, so whole buildings are phased. Bigger jobs take longer.
Landlords, agents and businesses in Wildhern
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What sealant work can’t fix
New sealant cannot fix everything, and we will tell you before we start. It will not solve:
- Poor ventilation that keeps bringing mould back
- Failed tanking or loose tiles behind the sealant
- Cracked trays or baths rather than failed joints
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
