Washroom sealing for Hunton sites

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

Building owners, agents and FMs in Hunton

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Washroom sealing in Hunton

Whether it’s a single toilet block in Hunton or a programme across several buildings, we work the same way: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. The enquiries we see most involve sealant lifting along a tray edge and black mould inside silicone joints that cleaning can’t shift, across urinals and WCs, kitchens and tea points and IPS panels and cubicles. Looking for mastic applicators who cover Hunton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Halls and community buildings near places like Hunton 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.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Hunton: questions and answers

Do hotels near Hunton have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

Do we have to close all our washrooms in Hunton for resealing?

Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.

Do you guarantee washroom sealing?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we’ll set out a timescale with the quote.

Is it OK to put new silicone on top of the old?

We strip every bit of the failed bead and wipe away the residue before resealing. It’s the difference between a joint that lasts and one that peels.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Panel boards already damaged by water
  • Loose panels, vanity units or tiles, which need fixing first
  • Failed tanking beneath a wet-room floor or behind tiles

If you are not sure, just phone 01277 525 020 or email us and we will give you a straight answer before you book.

Joints and surfaces we work on

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

What affects the price in Hunton

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

  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • How much there is to seal
  • Removal of failed or old sealant

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • The site address and postcode
  • The product your specification calls for

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or email drawings and photos.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. For a building around Hunton, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Related advice

When to call us in Hunton

Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and tell you if another trade is needed.

These are often picked up first by site or facilities staff:

  • Gaps where vanity tops meet the wall
  • Sealant laid over old silicone and now peeling
  • Discoloured joints around urinals and WC pans
  • Open joints at the base of cubicle panels

Halls linked to places like Church of St James host groups all week, which is hard on kitchen and toilet sealant.

What your quote should include

  • What the guarantee covers, and for how long
  • Who will actually carry out the work
  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing

How to choose a sealant contractor

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Clear standing water from shower floors where possible
  • Mention any site permits or estates rules at quote stage
  • Include joints in routine washroom inspections
  • Make sure washroom ventilation is running

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.

Keeping Hunton washrooms open while we work

Hunton is about 58 miles from central London, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open. Several hotels sit less than 2 miles from Hunton. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available.

For a hotel such as Norton Park Hotel, 1.1 miles to the north-west of Hunton, resealing en suites a few rooms at a time keeps the rest available.

Hunton is about 7 miles north of Winchester, in Hampshire. Businesses, contractors and managing agents in Hunton can call on us for washrooms and wet areas. Our Hampshire coverage takes in 723 places, large and small. We also cover Southampton, around 17 miles from Hunton.
