Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Cost factors for sealant joints

Each job is priced on its own details. The main factors are:

  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • The asbestos register, for older buildings
  • Clear photos of the problem areas
  • When you need the work done
  • Whether the building will be occupied during the work

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email us.

Sealant specialists in Steyning

Inside a commercial building, sealant does a lot of quiet work: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike, matching the sealant to the location instead of using one product throughout. The enquiries we see most involve window and door perimeter joints that have cracked open and black mould through washroom sealant that won’t clean off, on kitchen worktops and splashbacks, movement joints in walls and floors and window and door perimeters. Facilities teams, main contractors and managing agents in Steyning tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

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

In a smaller place such as Steyning, commercial buildings are typically a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. They’re not big jobs one by one, but their joints need the same preparation as anywhere.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

How a job runs

Where the site stays busy, 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. What matters most for a job in Steyning is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

Before we start on site

  • Move anything stored against the joints
  • Send any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000

Why it’s worth doing now in Steyning

Leaving a failed joint rarely saves money. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, which brings decorators and flooring contractors into the repair. Resealing while only the sealant has failed keeps the job small. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

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 quote and we will explain how it’s made up.

FAQs: Steyning

Do hotels near Steyning have to close for sealant work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Is Steyning too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can areas stay open during the work?

That comes down to planning: areas are phased, access windows agreed and enough washrooms or entrances left in use. Tell us what has to stay open and we will plan the job around it.

Do you check for asbestos before removing sealant?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Do you take on multi-site sealant work?

Yes, across South East England, Greater London and all of Scotland. One contact and one process for every building makes a portfolio easier to manage.

Surface by surface

Commercial kitchens and tea points

In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. They’re degreased thoroughly before resealing, with a food-safe or hygienic product wherever food contact can happen.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.

Signs you need commercial sealant contractors in Steyning

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed will all fail early. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

Typical triggers for a call:

  • Frame sealant that has cracked, shrunk or pulled away
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Earlier reseals applied straight onto the failed bead
  • Smeared sealant across finishes from a rushed job

Shops and cafés around stations like Lancing station (to the south of Steyning) trade from early, so work is timed around them.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • Whether old or failed sealant will be cut out, not overlaid
  • How long is the guarantee, and what does it include?
  • Can the work be phased to keep areas open?
