About our commercial sealant contractors in High Easter

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. The enquiries we see most involve damp patches where an external joint has failed and frame mastic that has hardened and come away from the wall, on washrooms and tea points, external facade joints and floor and threshold joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in High Easter, preparation and product choice get the time they need.

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

A job in a smaller place like High Easter is usually a single building. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Walls or slabs moving more than any sealant can take
  • Water from a services leak rather than a joint
  • Faulty windows rather than failed perimeter sealant

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly before you book.

Where we work in High Easter

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

What High Easter’s businesses ask us to seal

High Easter is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. At about 29 miles from central London, High Easter is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site.

If you run an office at a site such as Parklands Business Centre (2.6 miles west of High Easter), the sealant at reception desks, tea points and frames ages with each fit-out. A lasting commercial joint around High Easter begins with the old bead fully out and the faces clean and dry.

High Easter is about 7 miles north-west of Chelmsford, in Essex. Across the CM1 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Essex, 644 places are covered, High Easter among them. Sites around London have their own page, roughly 29 miles from High Easter.

Commercial sites across CM1 are covered. We cover commercial and managed buildings on The Street and Boreham Court. Just outside High Easter, we also work in Stagden Cross (1 mile east), High Roding (2 miles north-west), Keeres Green (2 miles west), Roundbush Green (2 miles west) and Great Canfield (2 miles north-west). Bigger towns within reach include Chelmsford (7 miles south-east), Braintree (10 miles north-east), Harlow (11 miles west), Brentwood (13 miles south), Maldon (15 miles east) and Billericay (13 miles south).

Why act early in High Easter

Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We’ll suggest an order, worst sealant joints first. Converted and older buildings near places like High Easter 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. Tell us how the joints are reached and call for a quote.

Why clients in High Easter choose us

  • CSCS-carded applicators
  • Colour agreed before work starts
  • Public liability insurance in place
  • A range of standard colours, depending on the product

Commercial clients in High Easter

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Act on the first lifting edges rather than waiting
  • On pre-2000 buildings, share the asbestos information before work starts
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Respect the cure time before reopening an area

Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet. It’s worth having fans checked while the sealant is fresh.

A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

Your questions answered

Is High Easter off your patch?

Not at all. High Easter is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you match sealant colours for premises in High Easter?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Which site documents can you send us?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Smaller jobs around High Easter can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.
