Commercial sealant contractors near Stonestreet Green

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

From enquiry to sign-off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Stonestreet Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First, details come to us: photos, 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. We strip the failed bead and prepare both faces of the joint.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we’ll be in
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • The size and state of each joint
  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • The product your specification calls for
  • The type of building and who uses it
  • The site address and postcode
  • Access details, including height

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send details through our quote form.

After the work

To get the most from the new sealant:

  • Make sure ventilation in wet areas is switched on and working
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Note dates and locations of sealant work for future planning
  • Add sealant to the planned maintenance inspection list

Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them. If that happens, ring 01277 525 020 or email drawings and photos and we’ll price putting it right.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

FAQs: Stonestreet Green

Can you supply sealant in our brand colour for a site in Stonestreet Green?

Yes, we can usually get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Is a smaller place like Stonestreet Green outside your area?

No. Places such as Stonestreet Green are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you work for facilities managers and managing agents?

Yes. Use our quote form to send the site details, or phone or email us.

What guarantee do you give on resealing?

The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Is it OK to apply fresh sealant over existing beads?

Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

What Stonestreet Green’s businesses ask us to seal

Less than 3 miles from Stonestreet Green there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal. Stonestreet Green sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

Sites a few miles apart, such as Evegate Business Park and Mersham-le-Hatch Business Village, can share one programme and one point of contact. Units at places like Ashford Retail Park (3 miles north-west of Stonestreet Green) are refitted as brands change, and the joints have to suit each new scheme. Offices at parks like Evegate Business Park (to the north of Stonestreet Green) have receptions, kitchens and glazed partitions where a tidy joint matters.

Work for main contractors and building owners

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

How the job changes by surface

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control; we install what’s specified.

Facade and cladding joints

Facade joints move every day as panels warm and cool. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
