About our commercial sealant contractors in Pound Hill

Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we’ll plan around them. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on window and door perimeters, movement joints in walls and floors and washrooms and tea points, and what we’re called in for most is untidy joints in a reception, shop floor or lobby and greasy, split joints in a kitchen or tea point. Facilities teams, main contractors and managing agents in Pound Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

We price commercial jobs in Pound Hill from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.

Sealant jobs for businesses in a place the size of Pound Hill are often best grouped: frontage, staff facilities and window perimeters on one booking. That keeps travel and disruption down.

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.

How the quote is worked out

What shapes the price:

  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses
  • Access and working height
  • The total length or number of joints

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • Anything awkward about access or site hours
  • The product your specification calls for
  • What the building is and how it’s used
  • Photos of the joints, close up and from further back

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or phone 01277 525 020 or email drawings and photos to discuss it first.

Your questions answered

Is Pound Hill too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Is Worth Corner Business Centre, near Pound Hill, within your area?

Yes. We cover Pound Hill and the area around it, including industrial estates, business parks and retail parks such as Worth Corner Business Centre. Photos and a short description are enough for a first look.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Do you check for asbestos before removing sealant?

On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility, and we don’t remove asbestos-containing materials.

Can areas stay open during the work?

It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we are sealing for as long as the cure needs.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Do you work directly for building managers?

Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off.

When it isn’t the sealant

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

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Broken glass or blown double-glazed units
  • Structural cracks or movement the joints weren’t designed for

If you are not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.

Surfaces we seal

  • Washrooms and tea points
  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • External facade joints
  • Movement joints in walls and floors
  • Window and door perimeters

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. Several jobs near Pound Hill can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings
  • Make sure the joints can be reached

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send details through our quote form with what you know.

Advice

What the job involves on each surface

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The new sealant is chosen for the movement and, on floors, the traffic.

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, phasing the rooms so not every toilet is closed at once.

Shops, offices and hotels in and around Pound Hill

Crawley, one of the planned towns of the twentieth century, takes in or adjoins Pound Hill. Commercial buildings from the planned-town decades tend to carry joints from several refits, not all of them matching. Pound Hill has three care or nursing homes no more than 2 miles away. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound; colours can be chosen to suit the interior.

Units at places like County Mall, 1.7 miles west of Pound Hill, are refitted as brands change, and the joints have to suit each new scheme. Shops and cafés around stations like Three Bridges station (0.6 miles south-west of Pound Hill) trade from early, so work is timed around them.

Pound Hill is about 2 miles north-east of Crawley, in West Sussex. Commercial clients in Pound Hill can call on us for sealant joints. Across West Sussex, 373 places are covered, Pound Hill among them. There’s a separate page for Brighton, roughly 20 miles from Pound Hill.

Postcode districts covered here: RH10 for sealant joints. Streets here include Worth Road, Burns Road and Milton Road. We also cover Worth (1 mile south), Three Bridges (1 mile south-west), Forge Wood (1 mile north), Maidenbower (1 mile south) and Copthorne (1 mile north-east). A short drive away, we cover Horsham (8 miles south-west), Haywards Heath (9 miles south), Burgess Hill (11 miles south), East Grinstead (6 miles east), Broadfield (3 miles south-west) and Billingshurst (15 miles south-west).

Do you need commercial sealant contractors in Pound Hill?

Outside, sunlight and rain wear sealant down year after year. Sunny elevations dry the surface out and exposed ones take driving rain; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.

Look out for the following:

  • A top-up bead over failed sealant, now lifting
  • Untidy joints in a reception, shop floor or lobby
  • Frame mastic that has hardened and come away from the wall
  • Mouldy silicone around WCs, urinals and vanity tops

Occupiers with premises at both Worth Corner Business Centre and Meadowbrook Industrial Estate could have the sealant at each handled under one quote.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Whether their applicators hold CSCS cards
  • Whether primer will be used where the manufacturer specifies it
  • The terms of the workmanship guarantee
