Washroom sealing across Hawthorn Hill

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

Washroom sealing in Hawthorn Hill, done properly

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. We work on urinals and WCs, kitchens and tea points and accessible toilets and changing rooms, and the failures we’re asked to look at most are failed sealant in a tea point or staff kitchen and stained sealant around pans and urinals. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hawthorn Hill, preparation and product choice get the time they need.

Farm shops, cafés and venues in converted rural buildings around places like Hawthorn Hill have busy toilets and kitchens. We plan the work around bookings and opening times.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Loose panels, vanity units or tiles, which need fixing first

If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.

Where we work in Hawthorn Hill

Questions we are asked in Hawthorn Hill

Can work at a site such as Newbold College of Higher Education fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Hawthorn Hill off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Do you work in hospitals, clinics and care homes?

Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

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. We don’t remove asbestos-containing materials.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Smaller jobs around Hawthorn Hill can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Agree which areas must stay open
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Quotes

Surface by surface

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and make the room look neglected.

For managing agents and facilities managers

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • How much existing material needs removing
  • Which sealant the job calls for
  • Joint width, depth and condition
  • Location, for remote and island sites

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

Sending details for a quote

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

  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • The product your specification calls for
  • Clear photos of the problem areas

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or send details through our quote form.

Leave it or put it right?

Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Around Hawthorn Hill, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What you get with us

  • Over 20 years of commercial sealing
  • Public liability insurance in place
  • RAL and finish matching where the product range allows
  • Work to your specification and the manufacturer’s guidance
