Why it’s worth doing now in Marshalswick
Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. Small buildings around Marshalswick suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

How the job changes by surface
IPS and cubicle panels
Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.
Wet-room floors and floor-to-wall joints
Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.

Questions about Marshalswick
Will you plan work around the academic year at somewhere like University of Hertfordshire?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Will our hotel in Marshalswick need to close for the work?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Is it possible to just clean mouldy silicone?
Normally not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacing the bead is the lasting answer.
What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Water escaping beneath the floor rather than through a joint
- Swollen or delaminated boards behind panels or vanity tops
- Leaking pipes, traps, wastes or cisterns, which need a plumber
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Common problems we fix in Marshalswick
Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.
What tends to prompt an enquiry:
- Sealant lifting along a tray edge
- Sealant laid over old silicone and now peeling
- Urinal joints that look unhygienic
- Stained or open joints at kitchen sinks and worktops
Customer toilets in retail centres such as Village Arcade St Albans, 1.7 miles south-west of Marshalswick, rarely close, so resealing is phased.
