About our washroom sealing in Baffins

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. We work on kitchens and tea points, vanity units and basins and accessible toilets and changing rooms, and the usual reasons a site gets in touch are open joints along basins and vanity units and sealant laid over old silicone and now peeling. One point of contact handles commercial sealant work in Baffins from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Pub and restaurant kitchens around smaller places like Baffins work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits. If neighbouring businesses or buildings around Baffins need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Preparing the site

  • Point out any areas we must not close
  • Share your working hours and any access restrictions
  • Move anything stored against the joints

Cost factors for washrooms and wet areas

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • The product specified
  • Whether old sealant has to be cut out first
  • How much there is to seal
  • Joint width, depth and condition

Whether it’s a single area or a whole estate, the same things set the price: 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.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Where the site is, with the postcode
  • Access details, including height
  • Drawings or a marked-up plan, if available
  • Any specification or named product

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, speak to us on 01277 525 020 or email drawings and photos.

Why act early in Baffins

Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. In a smaller place such as Baffins, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What you get with us

  • Fully insured
  • Specification-led, product-correct work
  • One contact handling all your sites
  • Colours confirmed for the specified product

Different surfaces, different methods

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Where food contact is possible, we use a hygienic, food-safe sealant.

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. Your infection-control and estates rules are followed and any permits the site uses.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Loose panels, vanity units or tiles, which need fixing first
  • Vanity carcasses that have swollen

If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think.

Joints and surfaces we work on

  • Kitchens and tea points
  • IPS panels and cubicles
  • Urinals and WCs
  • Vanity units and basins
  • Accessible toilets and changing rooms
  • Showers, trays and wet room floors

Owners, agents and contractors

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Sanitary sealant for Baffins buildings

Baffins lies within about 1 mile of the sea, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Bathrooms turned round daily in the busy months need sound, cleanable joints, so we plan the work for quieter weeks where possible. Baffins lies roughly 63 miles out from central London, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.

At a hotel such as Eastfield Hotel, which lies south of Baffins, the quieter weeks are the time to reseal bathrooms. For buildings on a site such as Copnor Bridge Business Centre, under half a mile west of Baffins, washrooms and tea points can be resealed in phases through the working week. At a university such as University of Portsmouth - Langstone Campus, 1 mile to the south-east of Baffins, summer is the usual window for resealing residence bathrooms.
