Commercial sealant contractors in Plastow Green

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

Cost factors for sealant joints

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

  • How much there is to seal
  • Distance, for remote addresses
  • The product specified
  • How much existing material needs removing

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • The product your specification calls for
  • Whether an asbestos survey exists
  • The type of building and who uses it
  • Approximate linear metres or a joint schedule

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Commercial sealant contractors for commercial buildings in Plastow Green

Inside a commercial building, sealant does a lot of quiet work: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building, picking the product for each location rather than one tube for everything. Most enquiries involve leaks that seem to come through a sealant line and sanitary sealant that has gone black and patchy, on kitchen worktops and splashbacks, movement joints in walls and floors and external facade joints. Facilities teams, main contractors and managing agents in Plastow Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

On a typical commercial building in Plastow Green, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.

Commercial sealant work around smaller places like Plastow Green 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.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Common questions from Plastow Green clients

Is Plastow Green too far out for you?

No. Places such as Plastow Green are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you offer colour-matched sealant for buildings in Plastow Green?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we’ll confirm what’s available for the product.

How do you keep disruption to occupiers down?

It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing for as long as the cure needs.

How many days will you need on site?

That varies with the scale of the job, but the work usually takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Jobs in and around smaller places like Plastow Green are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. We check the work with you, and the 12-month guarantee starts.

Getting the site ready

  • Send any specification or drawings in advance
  • Share the asbestos register for older buildings
  • Agree which areas must stay open

Leave it or put it right?

On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings. It shows over the following seasons rather than at handover. Converted and older buildings near places like Plastow Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why clients in Plastow Green choose us

  • Colour agreed before work starts
  • 12-month guarantee on workmanship

  • Failed material removed, not covered up

Different surfaces, different methods

Shop fronts and retail fit-outs

Shop fits put sealant right in front of clients. Counters, display units, shopfront frames and floor trims all need a neat line. Colour options are confirmed with the quote.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. Access, such as scaffold already up, is agreed before the price is fixed.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Water from a services leak rather than a joint
  • Old mastic that tests positive for asbestos

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly.

What we seal

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