Commercial sealant contractors for commercial buildings in Harbridge

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and on a working site that usually surfaces as a leak, a stain or a complaint from occupiers. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on external facade joints, floor and threshold joints and window and door perimeters, and what we are called in for most is shrunken sealant along kitchen worktops and splashbacks and leaks that seem to come through a sealant line. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Harbridge it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Commercial sealant work around smaller places like Harbridge tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Sealant on show in Harbridge’s commercial buildings

At least three named trading, business or retail sites lie within about 3 miles of Harbridge. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies. Rainfall across the South East, Harbridge included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For tenants and agents on sites such as Headlands Business Park, which lies south of Harbridge, office fit-outs, reception joints and window perimeters are the usual sealant work. Sites a few miles apart, such as Headlands Business Park and Fordingbridge Business Park, can share one programme and one point of contact.

How the quote is worked out

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

  • How accessible the joints are
  • Travel to remote or island sites
  • How much there is to seal
  • Backing rod, priming and other preparation

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • How the joints are reached, and at what height
  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available

To get a fixed quote, call the office on 01277 525 020 or use the quote form. Our quote form is another easy route.

Commercial clients in Harbridge

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.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Why act early in Harbridge

Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme. For buildings around smaller places like Harbridge, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Why choose Mastic Doctor in Harbridge

  • One contact handling all your sites
  • Workmanship guaranteed for 12 months
  • Colours confirmed for the specified product
  • Joints cleaned back to sound surfaces

Read what affects the cost or our accreditations and insurance.

Keeping the joints sound

To get the most from the new sealant:

  • Report cracked or peeling sealant early
  • Log reseals in the O&M or maintenance records
  • Respect the cure time before reopening an area
  • Keep washroom and kitchen extraction working

We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

Sealant installed at the same time normally fails in sequence. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We will tell you which sealant joints need doing first and which can wait.

How the job changes by surface

Fire-rated seals where specified

Fire-rated sealant is only one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services and gaps, so we’ll flag it if the detail needs a different product.

Shop fronts and retail fit-outs

Retail work typically has to fit around trading. Tell us your trading hours and access windows and we will plan around them, phasing areas so the shop floor stays usable.

Harbridge: questions and answers

Do you offer colour-matched sealant for buildings in Harbridge?

Yes, we can typically get close to most finishes from the product’s colour range. Send colour references or photos and we’ll confirm what’s available for the product.

Is Harbridge off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Is failed sealant stripped out, or sealed over?

Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

What about asbestos in old mastic?

Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you work directly for building managers?

Yes. A large share of our work comes through facilities managers, managing agents and landlords. Tell us how you issue work and we’ll fit in.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Harbridge, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Point out any areas we must not close
  • Arrange parking or a loading space
