Washroom sealing for Connaught Village sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Do you need washroom sealing in Connaught Village?

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead so it peels away quickly.

What tends to prompt an enquiry:

  • Sealant laid over old silicone and now peeling
  • Washrooms that look worn because of the sealant
  • Kitchen worktop joints that can’t be kept clean
  • Mould spotting along silicone joints

Student showers at universities like BPP University, under half a mile to the south-west of Connaught Village, see more use than most, and their silicone shows it.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • How long is the guarantee, and what does it include?
  • Can the work be phased to keep areas open?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

How we handle washroom sealing in Connaught Village

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. Site teams most often ask us about users noticing mouldy joints and failed sealant behind washroom basins, on IPS panels and cubicles, showers, trays and wet room floors and vanity units and basins. Looking for mastic applicators who cover Connaught Village? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

In a London area such as Connaught Village, commercial washrooms in offices, hotels and leisure buildings see constant use. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What the job involves on each surface

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and look unhygienic.

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.

Why it’s worth doing now in Connaught Village

Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

  • RAL and finish matching where the product range allows

Toilets, showers and kitchens around Connaught Village

London offices and hotels usually can’t close all their washrooms at once, so resealing goes floor by floor, agreed with the facilities team. Plenty of hotels sit less than 2 miles from Connaught Village. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest.

En suites at hotels like Griffin House Hotel, less than half a mile to the north-east of Connaught Village, are cleaned daily, which wears silicone over time. For a college such as London College of Fashion, 1 mile to the east of Connaught Village, half-term and summer give the windows for washroom work.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Your questions answered

Can you work in a London building with booked loading and goods-lift slots?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Do hotels near Connaught Village have to close for sealant work?

Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

Is there a guarantee on the work?

Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Do you cover Connaught Village?

Yes. We cover Connaught Village and the rest of Greater London. To discuss a job, speak to us on 01277 525 020 or send details through our quote form.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking between a morning and a week or so, set by the number of rooms and the phasing you need. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Preparing the site

Advice

Quoting for work in Connaught Village

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Backing rod, priming and other preparation
  • Which sealant the job calls for
  • Location, for remote and island sites
  • Quantities, in metres or numbers

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • Any specification or named product
  • The postcode of the building
  • What the building is and how it’s used
  • Anything awkward about access or site hours

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
