Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Steventon, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Old sealant is cut out completely, never sealed over.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

What we need from you

  • Warn occupants and staff about the work
  • Send your site hours and access windows
  • Explain the parking and delivery arrangements

Advice

About our commercial sealant contractors in Steventon

Most of the buildings we seal stay open while we are there. Tell us your site hours and access windows and we will plan around them; phasing keeps some washrooms, kitchens or entrances available while others are done. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you have layers of sealant, all of them failing and hardened, chalky sealant on south-facing or exposed elevations, we can put it right, on movement joints in walls and floors, window and door perimeters and external facade joints alike. For commercial sealant work in Steventon, you deal with one contact from quote to sign-off, whether it’s one building or several.

If you look after more than one building near Steventon, the work can be planned as one programme, with one quote format and one point of contact.

In and around smaller places such as Steventon, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Signs you need commercial sealant contractors in Steventon

No sealant joint is permanent. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. On a busy commercial site several of those pile up at once.

Site and facilities staff are often the first to spot these:

  • A top-up bead over failed sealant, now lifting
  • Water staining near frames, panels or ceilings
  • Wall and floor joints that have lost their seal
  • Mouldy silicone around WCs, urinals and vanity tops

Shops and cafés around stations like Didcot Parkway station, 3.6 miles to the east of Steventon, trade from early, so work is timed around them.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing
  • How they’ll work around occupants
  • Is the sealant right for the movement and the substrate?

Our contractor checklist

What sets the cost

We price every job individually. The things that drive the figure:

  • Which sealant the job calls for
  • Phasing around occupants
  • How much existing material needs removing
  • Travel to remote or island sites

Cost follows what’s involved: 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.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • The postcode of the building
  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Any specification or named product

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or use the quote form.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Broken glass or blown double-glazed units
  • Suspect materials that need testing and specialist removal

If in doubt, phone 01277 525 020 or send photos by email and we’ll say what we think before you book.

Where we work in Steventon

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

Keeping the joints sound

After handover, a little attention goes a long way:

  • Respect the cure time before reopening an area
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Look at the sealant around anything that has been moved or replaced
  • Make sure contractors see the asbestos survey before cutting out old mastic

Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records.

In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

What Steventon’s businesses ask us to seal

Rainfall across the South East, Steventon included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. The 3 miles around Steventon take in two named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen.

Refits at hotels like Steventon House Hotel, 0.9 miles to the south-east of Steventon, bring joints at vanity tops, bars and reception desks that guests see every day. If you have premises on more than one site, say at The Core Business Centre and Trident Business Park, one contractor and one quote can cover both.

Yes. Estates, retail parks and business parks around Steventon, The Core Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Yes. You can send details through our quote form.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it.

What guarantee do you give on resealing?

Each job sits under our 12-month guarantee from handover. Keeping joints clean and inspected helps them last well beyond that.
