Need commercial sealant contractors in Little Dunmow?

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

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For a job in Little Dunmow, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.

  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. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Send your site hours and access windows
  • Flag any permit to work we will need
  • Clear stock, furniture or equipment away from the joints

How we handle commercial sealant contractors in Little Dunmow

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested. Most enquiries involve expansion joints with the sealant torn out and layers of sealant, all of them failing, across kitchen worktops and splashbacks, floor and threshold joints and washrooms and tea points. A single leaking joint is often how a building in Little Dunmow first comes to us: we look at the rest while we’re there and tell you what we find.

Quotes for commercial sealant in Little Dunmow can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.

In a smaller place such as Little Dunmow, commercial buildings are usually a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

How the job changes by surface

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photographs or a site visit tell us what’s needed, and 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. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Old mastic that tests positive for asbestos
  • Water from a services leak rather than a joint
  • Faulty windows rather than failed perimeter sealant

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think before you book.

Surfaces we seal

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

Should maintenance staff do it?

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.

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.

Your questions answered

Can the sealant on our Little Dunmow premises match the finishes?

Yes, we can usually get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.

Do you cover business parks and estates near Little Dunmow, such as Martels Industrial Estate?

Yes. Estates, retail parks and business parks around Little Dunmow, Martels Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

Can areas stay open during the work?

Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing, until its cure time has passed.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you work for facilities managers and managing agents?

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

What site paperwork can you provide?

The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.

What happens if it’s left?

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. In a smaller place such as Little Dunmow, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Pricing sealant joints depends on how many there are, their condition and the access. Call for a quote.
