What affects the price in Stratfield Mortimer

A fixed quote reflects the actual work. It allows for:

  • Any access equipment needed
  • Phasing around occupants
  • Location, for remote and island sites
  • Induction, permit and paperwork requirements

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • What the building is and how it’s used
  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older
  • When you need the work done

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email drawings and photos.

Commercial sealant contractors in Stratfield Mortimer

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. Site teams most often ask us about messy, uneven beads from earlier work that let the building down and damp patches where an external joint has failed, across floor and threshold joints, movement joints in walls and floors and external facade joints. Most enquiries from Stratfield Mortimer start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

On a typical commercial building in Stratfield Mortimer, 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 Stratfield Mortimer 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Shops, offices and hotels in and around Stratfield Mortimer

The South East is one of the drier parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Stratfield Mortimer is about 42 miles from central London.

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Cracking that needs a structural engineer to look at it
  • Broken glass or blown double-glazed units
  • A dripping trap, valve or pipe behind a fitting

If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

What the job involves on each surface

Facade and cladding joints

Facade joints move every day as panels warm and cool. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control.

Questions about Stratfield Mortimer

What site paperwork comes with a job in Stratfield Mortimer?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is a smaller place like Stratfield Mortimer outside your area?

No. Places such as Stratfield Mortimer are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What do you need from us to quote?

Send photographs, drawings or a list of locations through our quote form. If a visit is needed we’ll book one, and a fixed quote follows.

What about asbestos in old mastic?

It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.

Do you take on multi-site sealant work?

Yes. We take on runs of jobs across portfolios as well as single sites, quoted per building or as a package.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes a few hours to several days on most single sites, depending on joint lengths and access. For bigger or phased jobs, we’ll set out a timescale with the quote.

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites around Stratfield Mortimer. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Check sealant as part of routine building inspections
  • Keep washroom and kitchen extraction working
  • Keep a record of which joints were resealed and when
  • Look at the sealant around anything that has been moved or replaced

New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth, so we confirm it for each area at handover. Leaving the area closed until then keeps the bead neat.

Sealant rarely fails all at once across a building. A few splits this year normally mean more next year so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For work around Stratfield Mortimer, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First, details come to us: photographs, drawings or a schedule of the areas, and a site visit is booked where it helps.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Let building users know which areas are affected
  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints
