Commercial sealant contractors for businesses in Hillborough

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

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. For a site in Hillborough, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  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. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Send your site hours and access windows
  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements

Advice

Commercial sealant contractors in Hillborough

Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phased work can also be planned so areas stay in use. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. Site teams most often ask us about smeared sealant across finishes from a rushed job and damp patches where an external joint has failed, on floor and threshold joints, washrooms and tea points and kitchen worktops and splashbacks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hillborough it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Multi-site clients with buildings in and around Hillborough can put several sites on one programme, so standards and paperwork match across every site.

Small businesses near places like Hillborough frequently occupy converted farm buildings. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Commercial clients in Hillborough

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

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Hillborough can sit alongside others in a wider programme.

Leave it or put it right?

It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

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’ll explain how it’s made up.

Why clients in Hillborough choose us

  • Joints cleaned back to sound surfaces
  • Health and safety: CHAS accredited
  • Work to your specification and the manufacturer’s guidance
  • Commercial sealant work since 2005

Shops, offices and hotels in and around Hillborough

Hillborough is within about 1 mile of the coast. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Where a frontage needs a particular colour, the product still has to suit that exposure. Hillborough sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Occupiers with premises at both Eddington Business Park and Chislet Business Park could have the sealant at each handled under one quote. If you run an office at a site such as Eddington Business Park (2.1 miles west of Hillborough), the sealant at reception desks, tea points and frames ages with each fit-out. Offices and shops close to stations such as Herne Bay station, 2.2 miles west of Hillborough, tend to be busy all day, so sealant work is planned around opening hours.

Hillborough is about 2 miles east of Herne Bay, in Kent. We send applicators to Hillborough for sealant joints, handled exactly as we handle every other area. Our Kent coverage takes in 931 places. Our London page has more on work in that area, about 55 miles away.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • The site’s rules and procedures
  • Removal of failed or old sealant
  • Working within restricted access windows
  • Which sealant the job calls for

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done

  • Specification clauses that apply

Questions we’re asked in Hillborough

Is Hillborough off your patch?

No. Places such as Hillborough are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Does the sea air around Hillborough change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Can you take on work for an FM or managing agent?

Yes. A large share of our work comes through facilities managers, managing agents and landlords. We can work to your instruction process and site rules.

Can one contractor look after sealant on all our buildings?

Yes. Give us the sites and the scope at each, and we will put together a fixed quote and a sensible order of work.

What do you need from us to quote?

The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.

What guarantee do you give on resealing?

The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.

Is it OK to apply fresh sealant over existing beads?

Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip, and the faces are brought back to sound, dry material before resealing.

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

What the job involves on each surface

Movement joints in walls and floors

Movement joints in walls and floors let the structure expand and contract. When the seal fails, debris gets in and the joint stops working. The joints are resealed using a sealant matched to the movement and any traffic.

Window and door perimeters

Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t, matched to the frame colour where colour matters.
