Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Leave squeegees in busy showers
- Keep a record of which rooms were resealed and when
- Give housekeeping the cure time for every room
- Keep extractor fans working and serviced
Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints.
Signs to look for: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.
What sealant work cannot fix
We will always be straight with you, so here’s what new sealant won’t do:
- Cracked trays or baths rather than failed joints
- Failed tanking or loose tiles behind the sealant
- Faulty shower valves and leaking traps
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.

Do you need commercial sealant in Sunbury-on-Thames?
Larger buildings move, and lightweight partitions flex more than masonry. The sealant between walls, trays and fittings absorbs that strain and eventually tear.
Most people get in touch when they notice something like this:
- Mouldy washroom sealant that staff and guests notice
- Split sealant around staff kitchen worktops and sinks
- Joints that need doing before an inspection or audit
- Large numbers of bathrooms needing the same work
Community buildings like St Saviour are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

How it works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a single washroom, longer for a whole building. In Sunbury-on-Thames, 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 by looking at the rooms and agreeing what’s needed.
- 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.
Before we arrive
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Keep children and pets away from the work area

Advice
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
