About commercial sealant contractors in CM23

Sealant joints are easy to overlook until one lets water in. We are commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in CM23. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on kitchen worktops and splashbacks, floor and threshold joints and external facade joints, and what we are called in for most is weathered facade sealant that no longer flexes and water staining near frames, panels or ceilings.

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  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. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

What you’ll pay

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Commercial premises across CM23

Shop fits, office refurbishments and hotel refits in towns such as Bishop's Stortford, Stansted Mountfitchet and Bentfield Green all leave joints that need sealing. Where the joint is on show, a colour that suits the finish is part of the job.

Around the motorway corridors of the South East, business parks and industrial estates are common, and we cover CM23 along with the rest of the region.

Bishop's Stortford: On a business park such as Twyford Business Centre, 0.8 miles to the south-east of Bishop's Stortford, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. For premises near Bishops Stortford station, which lies south-east of Bishop's Stortford, footfall is part of the plan: work is phased so shops and offices keep trading.

Looking after the joints

For the best life from the joints:

  • Check joints after other trades have worked nearby
  • Don’t let cleaning or traffic back on before the cure time is up
  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Have extract fans checked so wet areas dry out

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, and we confirm it when each area is handed back. Leaving the area closed until then keeps the bead neat.

Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.

Signs you need commercial sealant contractors

External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges. A hardened bead can’t follow the building any more.

Common reasons buildings call us in:

  • Gaps behind commercial kitchen worktops and sinks
  • Layers of sealant, all of them failing
  • Expansion joints with the sealant torn out
  • Frame sealant that has cracked, shrunk or pulled away

What sets the cost

Each job is priced on its own details. The main factors are:

  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • The product specified

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Your programme or deadline
  • What the building is and how it’s used
  • Access details, including height
  • The asbestos register, for older buildings

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. CM23 can form part of a wider programme across Hertfordshire.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Your questions answered

Do you seal on top of existing 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.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Will the building have to shut during the work?

Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Does commercial sealant work come with a guarantee?

The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.

How do we get a quote?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.
