Sanitary sealant for Henwood buildings

The 2 miles around Henwood include two care or nursing homes. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Work is agreed with the manager, around residents’ routines. At about 55 miles from central London, Henwood is within reach of the capital, 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.

For a campus such as Azad University in Oxford (3.7 miles north-west of Henwood), showers in residences and washrooms in teaching blocks can be programmed around term dates. Where you are responsible for a hall attached to a building such as Church of St Peter, its kitchen and toilets need sealant that stays cleanable. Clinical washrooms at sites like Abingdon Community Hospital (3.2 miles south of Henwood) are scheduled with the ward so the room is out of use for as little time as possible.

Henwood is about 3 miles north-west of Abingdon-on-Thames, in Oxfordshire. We cover commercial sites throughout Henwood, for single jobs and planned programmes alike. Henwood is one of 423 places in Oxfordshire on our list.

Commercial sites across OX1 are covered. Among the streets we cover are Cumnor Road, Hill View Lane and White Hill Lane, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Wootton (1 mile south), Cumnor (1 mile north-west), Chawley (1 mile north), Appleton (2 miles west) and Dean Court (2 miles north). Further afield, our area takes in Oxford (5 miles north-east), Didcot (8 miles south-east), Bicester (15 miles north-east), Abingdon-on-Thames (3 miles south-east), Witney (9 miles north-west) and Carterton (12 miles west).

Washroom sealing in Henwood

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. We work on showers, trays and wet room floors, IPS panels and cubicles and urinals and WCs, 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. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Henwood is the same: the right product in a properly prepared joint.

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

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Questions about Henwood

Is Henwood off your patch?

No. Places such as Henwood are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you take on a job at a hospital such as Abingdon Community 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.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we will set out a timescale with the quote.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

What do you charge?

We don’t publish prices, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

Do you work in hospitals, clinics and care homes?

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

Honest limits

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

  • Leaks through tanking or membranes below the finishes
  • Fittings that move too much to hold a bead
  • Mould caused by poor ventilation, which will return until the extract is fixed

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What we seal

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

What the job involves on each surface

Showers and trays

If a tray moves too much or is cracked, it needs attention first, and we will say so before resealing.

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone, so the product is chosen to suit.

Why deal with it now?

Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. For buildings around smaller places like Henwood, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Why clients in Henwood choose us

  • CSCS-carded applicators
  • Matching to RAL references, product permitting
  • Commercial sealant work since 2005
  • Products installed to the manufacturer’s instructions

Read our cost guide and how we’re accredited.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Henwood, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Before we start on site

  • Have the specification and drawings to hand
  • Let us know about inductions and permits
  • Explain the parking and delivery arrangements
