Commercial sealant contractors across Otham

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

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Redoing a failed joint normally costs more than getting it right at the outset, 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.

About our commercial sealant contractors in Otham

Getting a price for commercial sealant contractors in Otham doesn’t need to be drawn out. Send photos, drawings or a schedule of the joints through our quote form and you can also speak to us on 01277 525 020 or send details through our quote form to talk it through. If the joints need seeing in person, a site visit comes first, followed by a fixed quote rather than an estimate that drifts. If you are dealing with gaps behind commercial kitchen worktops and sinks and window and door perimeter joints that have cracked open, we can help. A single leaking joint is often how a building in Otham first comes to us: we look at the rest while we are there and tell you what we find.

Occupied buildings in Otham need the work phased: we agree the order with you and hand back each area with its cure time.

Around smaller places such as Otham, small firms often work from converted barns, yards and rural units. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Shops, offices and hotels in and around Otham

Otham has two care or nursing homes no more than 2 miles away. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean. Otham has at least three named business or industrial parks inside a 3-mile radius. Each new occupier on a park like these tends to refit, from reception to staff kitchen.

Units at places like The Mall Maidstone, 2.6 miles north-west of Otham, are refitted as brands change, and the joints have to suit each new scheme. Offices and shops close to stations such as Bearsted station, 2.1 miles north of Otham, tend to be busy all day, so sealant work is planned around opening hours.

Otham is about 2 miles south-east of Maidstone, in Kent. Looking for commercial sealant contractors in Otham? We can help. We work across 931 places in Kent. We also cover London, some 33 miles away.

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. What matters most for a job in Otham is a clear list of what needs doing. A fixed quote follows.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Before we start on site

  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Otham: questions and answers

Is a smaller place like Otham outside your area?

Not at all. Otham is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Will our hotel in Otham need to close for the work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do you work for facilities managers and managing agents?

Yes. FMs, managing agents and landlords are among our regular clients, alongside main contractors. Tell us how you issue work and we will fit in.

Can you handle sealant work across several sites?

Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Signs you need commercial sealant contractors in Otham

The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.

What tends to prompt an enquiry:

  • Damp patches where an external joint has failed
  • Messy, uneven beads from earlier work that let the building down
  • A top-up bead over failed sealant, now lifting
  • Expansion joints with the sealant torn out

Trade counters and showrooms on estates such as Park Wood Trading Estate, 0.5 miles south of Otham, need neat joints where clients see them.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • What level of public liability insurance do they hold?
  • Health and safety accreditation such as CHAS
  • Their approach to joint depth and backing

Questions to ask before you appoint anyone

Why it’s worth doing now in Otham

Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s usually close behind. Where it helps, we quote a patch and a full reseal side by side. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

How the job changes by surface

Shop fronts and retail fit-outs

Shop fits put sealant right in front of customers. Joints around counters, displays and shopfront frames have to look tidy as well as seal, frequently colour-matched to the fit-out. We’ll confirm the colours available for the specified product.

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control, and we install to the specification.
