Busy facilities in and around Newpound Common

At about 37 miles from central London, Newpound Common is within reach of the capital, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

Welfare facilities in units on estates such as Billingshurst Trade Park, 1.9 miles east of Newpound Common, have showers, toilets and kitchens with sealant that works hard. Schools such as Wisborough Green Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays. Church halls and community buildings, such as those at The Parish Church of St Peter Ad Vincula, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

About our washroom sealing in Newpound Common

Whether it’s a single toilet block in Newpound Common or a programme across several buildings, the route is the same: send details, get a fixed quote, we seal, guaranteed. A few photos and a count of fittings are enough for a quick quote, or we can arrange a visit. If you have kitchen worktop joints that can’t be kept clean and panel joints letting water behind, we can put it right, on IPS panels and cubicles, kitchens and tea points and accessible toilets and changing rooms alike. Searching for sealant specialists in Newpound Common? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

In and around smaller places like Newpound Common, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Newpound Common, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints
  • Let us know about inductions and permits

Request a quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

How the quote is worked out

Before we quote, we look at:

  • The product specified
  • Phasing around occupants
  • Joint width, depth and condition
  • Quantities, in metres or numbers

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Sending details for a quote

A few photographs plus some basic facts will normally do. Please tell us:

  • Asbestos survey details if the building is older
  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or send photos by email.

Honest limits

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

  • Condensation from failed extract fans
  • Vanity carcasses that have swollen
  • Hollow tiles or loose panels behind the joint

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

What we seal

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

After the work

A few simple habits keep the new joints working:

  • Clean sealant with gentle products and a soft cloth
  • Keep washrooms out of use until we say the sealant has cured
  • Act on the first split you see at a shower tray
  • Photograph and log failed joints across the estate

Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

How the job changes by surface

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant, and we survey them together.

Your questions answered

Do we have to close all our washrooms in Newpound Common for resealing?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Could you schedule work at a campus like Brinsbury College for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Can you reseal washrooms in healthcare buildings?

We do. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

Do you cover Newpound Common?

Yes. We cover Newpound Common, and the simplest way to start is to speak to us on 01277 525 020 or email us.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Leave it or put it right?

Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Halls, stores and units around places like Newpound Common may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
