About our washroom sealing in Dry Sandford

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. Site teams most often ask us about washrooms that look worn because of the sealant and open joints along basins and vanity units, on showers, trays and wet room floors, accessible toilets and changing rooms and IPS panels and cubicles. Whoever orders the work in Dry Sandford, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Dry Sandford still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

From enquiry to sign-off

Tell us your site hours and access windows and we will 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. Rural sites near Dry Sandford may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  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. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Let building users know which areas are affected
  • Send any specification or drawings in advance
  • Arrange parking or a loading space

Wet areas in Dry Sandford’s workplaces

Dry Sandford is about 55 miles from central London, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

Healthcare estates like Abingdon Community Hospital, 2.2 miles to the south-east of Dry Sandford, expect contractors to follow their permits and cleaning rules in every washroom. At a college such as Abingdon & Witney College: Abingdon Campus, which lies south-east of Dry Sandford, washroom and kitchen sealant is best renewed in the holidays or in phases during term. For a hotel such as The Dog House Hotel, 1.5 miles south-west of Dry Sandford, resealing en suites a few rooms at a time keeps the rest available.

Dry Sandford is about 2 miles north-west of Abingdon-on-Thames, in Oxfordshire. We send applicators to Dry Sandford for washrooms and wet areas, handled exactly as we handle every other area. Dry Sandford is one of 423 places in Oxfordshire on our list for washrooms and wet areas.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Photograph and log failed joints across the estate
  • Make sure washroom ventilation is running
  • Don’t leave trays and floors sitting wet
  • Respect the cure time before reopening each room

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Building owners, agents and FMs in Dry Sandford

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Panel boards already damaged by water
  • Leaks through tanking or membranes below the finishes
  • Fittings that move too much to hold a bead

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

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

Questions about Dry Sandford

Could you schedule work at a campus like Azad University in Oxford for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can you work on a hospital site such as Abingdon Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Can you quote from photographs?

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

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

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

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

When can showers be used after new sealant?

Each sealant has a cure time before it should get wet. We plan the phasing around that so facilities are never short.

Will all the toilets be closed at once?

Only the area we are working in is closed. Rooms go back into use once the sealant has cured, then we move on.
