Need commercial sealant contractors in Throwley Forstal?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Structural cracks or movement the joints weren’t designed for
  • Suspect materials that need testing and specialist removal
  • Broken glass or blown double-glazed units

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Surfaces we seal

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

Commercial sealant contractors in Throwley Forstal

Most of the buildings we seal stay open while we are there. Tell us your site hours and access windows and we will plan around them; phasing keeps some washrooms, kitchens or entrances available while others are done. That applies whether the building is an office, a shop, a hotel, a college or a care home. If you are dealing with earlier reseals applied straight onto the failed bead and untidy joints in a reception, shop floor or lobby, we can put it right, on kitchen worktops and splashbacks, movement joints in walls and floors and floor and threshold joints alike. A specialist sealant contractor works differently from a general builder: in Throwley Forstal, that means joint design, primers and backing rod as standard.

If you look after more than one building near Throwley Forstal, the work can be planned as one programme, so standards and paperwork match across every site.

Commercial sealant work around smaller places like Throwley Forstal 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.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Cost factors for sealant joints

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • The product specified
  • Joint width, depth and condition
  • Removal of failed or old sealant
  • Location, for remote and island sites

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Before you send an enquiry

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

  • Rough lengths or quantities, or drawings if you have them
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists
  • Any dates the work must fit around

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Frontages, fit-outs and joints in Throwley Forstal

Throwley Forstal sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Throwley Forstal lies roughly 44 miles out from central London. Business parks and retail centres are common around the capital’s motorway corridors. If you have premises across the region, one contractor can cover them all.

Premises within reach of Selling station, 4.1 miles east of Throwley Forstal, often have busy frontages where joints are seen by everyone passing.

Different surfaces, different methods

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price.

Movement joints in walls and floors

Movement joints in walls and floors let the structure expand and contract. Failed seals let grit and water in, and the edges start to suffer. The joints are resealed using a sealant matched to the movement and any traffic.

When to call us in Throwley Forstal

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

It’s worth sending us details if you spot any of the following:

  • Gaps behind commercial kitchen worktops and sinks
  • Wall and floor joints that have lost their seal
  • Sanitary sealant that has gone black and patchy
  • Earlier reseals applied straight onto the failed bead

For any commercial premises in Throwley Forstal, a lasting joint depends on full removal of the old sealant and clean, dry faces.

Questions about Throwley Forstal

Can you match sealant colours for premises in Throwley Forstal?

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 photos and we’ll confirm what’s available for the product.

Is Throwley Forstal too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can areas stay open during the work?

We phase the work so parts of the building stay open. Tell us your site hours and access windows and we’ll plan around them.

Is failed sealant stripped out, or sealed over?

The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Is your work guaranteed?

Our workmanship is guaranteed for 12 months. We’re fully insured for public liability as well.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

From enquiry to 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 Throwley Forstal can be grouped with others nearby. You will have a fixed quote before work starts.

  1. You send photos, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. We strip the failed bead and prepare both faces of the joint.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.
