Common questions from Lower Denford clients

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

Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.

Does a hotel in Lower Denford need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you guarantee washroom sealing?

There is a 12-month guarantee on our workmanship, and we carry public liability insurance.

Is old silicone taken out first?

The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

About our washroom sealing in Lower Denford

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. If you have open joints along basins and vanity units and users noticing mouldy joints, we can put it right, on kitchens and tea points, IPS panels and cubicles and urinals and WCs alike. Searching for sealant specialists in Lower Denford? We have been sealing commercial buildings since 2005.

Rural businesses near smaller places such as Lower Denford, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we’ll plan around them.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. If others near Lower Denford need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  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 us know about inductions and permits
  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance

Related advice

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

After the work

A few simple habits keep the new joints working:

  • Add sealant joints to planned maintenance checks
  • Keep extract fans working and vents clear
  • Leave signs up until the cure time is over
  • Clean sealant with gentle products and a soft cloth

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Why deal with it now?

When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Older rural buildings around Lower Denford move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Panel boards already damaged by water
  • Hollow tiles or loose panels behind the joint
  • Water escaping beneath the floor rather than through a joint

If you are not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer.

Surfaces we seal
