Quoting for work in Longfield Hill
Each job is priced on its own details. The main factors are:
- Any access equipment needed
- Phasing around occupants
- The size and state of each joint
- Location, for remote and island sites
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
- Specification clauses that apply
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
How we handle washroom sealing in Longfield Hill
When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. The enquiries we see most involve resealing that didn’t last because the old bead stayed and stained sealant around pans and urinals, across urinals and WCs, kitchens and tea points and vanity units and basins. Facilities teams, main contractors and managing agents in Longfield Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Halls and community buildings near places like Longfield Hill are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface
Kitchens and tea points
Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sealed joints leave no gaps for food and dirt.
Showers and trays
If a tray moves too much or is cracked, it needs attention first, and we will say so before resealing.
Questions about Longfield Hill
Is Longfield Hill too far out for you?
Not at all. Longfield Hill is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work around term dates at a campus such as University of Greenwich?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Can washrooms stay open while you work?
The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we will plan around them.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. If others near Longfield Hill need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- We agree which rooms close and when, so users always have somewhere to go.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
Preparing the site
- Send any specification or drawings in advance
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000

What we can’t put right

- Swollen or delaminated boards behind panels or vanity tops
If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.
What we seal

Halls linked to places like Church of St Mildred host groups all week, which is hard on kitchen and toilet sealant. Clinical washrooms at sites like Gravesham Community Hospital (to the north of Longfield Hill) are scheduled with the ward so the room is out of use for as little time as possible. Office washrooms on sites such as Fawkham Business Park (to the west of Longfield Hill) are in use all working day, so resealing is phased to keep some open.

Why deal with it now?
Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. For buildings around smaller places like Longfield Hill, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
