Washroom sealing in Northfield, done properly

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. We are fully insured. Every resealed washroom carries our 12-month guarantee. We work on kitchens and tea points, vanity units and basins and showers, trays and wet room floors, and what we’re called in for most is stained sealant around pans and urinals and washrooms that look worn because of the sealant. Whoever orders the work in Northfield, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Ground-floor premises below tenements in Scotland’s cities often have small staff toilets and kitchens. Compact, poorly ventilated rooms are hard on sealant.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

What the job involves on each surface

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. We work to your estates and infection-control requirements as well as site permits.

Wet-room floors and floor-to-wall joints

We seal the visible joints; we don’t install or repair waterproofing below, and we will say if the trouble looks to be beneath the floor.

What we are called out for in Northfield

Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and say if it needs a plumber or another trade.

Common reasons buildings call us in:

  • Kitchen worktop joints that can’t be kept clean
  • Urinal joints that look unhygienic
  • Mould spotting along silicone joints
  • Washrooms that look worn because of the sealant

For a hotel such as Britannia Hotel, which lies north of Northfield, resealing en suites a few rooms at a time keeps the rest available.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards

Our contractor checklist

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

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

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Why it’s worth doing now in Northfield

A tired washroom says a lot about how a building is run. Visitors notice black sealant before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. In a tenement or shared city building, water from a failed joint can reach other owners’ property. Acting early avoids disputes and bigger repairs.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why clients in Northfield choose us

  • A range of standard colours, depending on the product
  • 12 months’ guarantee on every job
  • Sealing commercial buildings since 2005
  • Our applicators hold CSCS cards

Keeping Northfield washrooms open while we work

Northfield is on Scotland’s drier eastern side. Mould in sanitary sealant comes down to ventilation and use more than the weather outside. There are a good number of hotels within about 2 miles of Northfield. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available.

At a school such as Northfield Academy, changing rooms and kitchens need cleanable joints as much as the toilets. For buildings on a site such as Twin Spires Business Park, 0.7 miles north of Northfield, washrooms and tea points can be resealed in phases through the working week.

Northfield is about 2 miles north-west of Aberdeen, in Aberdeen. Commercial clients in Northfield can call on us for washrooms and wet areas, as part of our coverage of Aberdeen. We work across 40 places in Aberdeen, large and small.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. City jobs in Northfield normally need parking and loading planned. Tenement closes, shared stairs and factor approvals may also be involved.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Before we start on site

  • Explain the parking and delivery arrangements

  • Tell staff and tenants when we’ll be in

FAQs: Northfield

Do hotels near Northfield have to close for sealant work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

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

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Do you cover Northfield?

Yes. Northfield falls within our area, and the simplest way to start is to speak to us on 01277 525 020 or email a schedule or drawings.
