Washroom sealing for businesses in Kencot

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

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • How accessible the joints are

We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • The product your specification calls for
  • When you need the work done
  • The asbestos register, for older buildings
  • The type of building and who uses it

For a fixed quote, phone 01277 525 020 or email us, telling us the site location and the nature of the job. You can also send details through our quote form.

Washroom sealing in Kencot, done properly

Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. We work on vanity units and basins, kitchens and tea points and urinals and WCs, and the failures we are asked to look at most are mould spotting along silicone joints and users noticing mouldy joints. Searching for sealant specialists in Kencot? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Halls and community buildings near places like Kencot are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Wet areas in Kencot’s workplaces

Central London is about 67 miles from Kencot. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

For a hall at a building such as Church of St Peter, resealing the kitchen and toilets can be fitted between bookings. On an industrial estate such as Carterton South Industrial Estate, 1 mile to the north-east of Kencot, staff toilets, showers and canteens are where sanitary sealant takes the most wear. For a school such as St Peter's Church of England School, washroom and kitchen sealant can be renewed around term dates.

Kencot is about 2 miles south-west of Carterton, in Oxfordshire. Our applicators travel to Kencot for work on washrooms and wet areas, handled exactly as we handle every other area. We work across 423 places in Oxfordshire, from busy centres to rural villages. Sites around Oxford have their own page, roughly 16 miles from Kencot.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

FAQs: Kencot

Is Kencot too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work on a hospital site such as Longworth Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can you clean the mould off instead of resealing?

Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

Will you quote for a small job?

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.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Kencot need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.

Related advice

Leave it or put it right?

When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Around Kencot, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Why choose Mastic Doctor in Kencot

  • Public liability insurance in place

Read our cost guide and how we’re accredited.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Mention any site permits or estates rules at quote stage
  • Keep extract fans working and vents clear
  • Don’t leave an open joint at a basin or tray
  • Keep washrooms out of use until we say the sealant has cured

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Swollen or delaminated boards behind panels or vanity tops
  • Hollow tiles or loose panels behind the joint
  • Failed tanking beneath a wet-room floor or behind tiles

Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly.

Joints and surfaces we work on

  • Kitchens and tea points
