Commercial sealant contractors for commercial buildings in Ham

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, because the duty to manage asbestos sits with the dutyholder. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). If you have frame sealant that has cracked, shrunk or pulled away and smeared sealant across finishes from a rushed job, we can put it right, on washrooms and tea points, window and door perimeters and kitchen worktops and splashbacks alike. A specialist sealant contractor works differently from a general builder: on jobs in Ham, preparation and product choice get the time they need.

On a typical commercial building in Ham, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

In and around smaller places such as Ham, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Location, for remote and island sites
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • What the building is and how it’s used
  • How the joints are reached, and at what height

To get a fixed quote, call the office on 01277 525 020 or send photos by email. You can also send details through our quote form.

Should maintenance staff do it?

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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Ham can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with the evidence: photos, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

What we need from you

  • Arrange parking or a loading space
  • Flag any permit to work we will need
  • Tell staff and tenants when we will be in

Quotes

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Advice

Ham: questions and answers

Do you cover business parks and estates near Ham, such as Birnham Farm Business Centre?

Yes, sites like Birnham Farm Business Centre are within our area, along with the rest of Ham. Photos and a short description are enough for a first look.

Is a smaller place like Ham outside your area?

Not at all. Ham is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

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.

Can you supply RAMS and insurance details?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

How do you keep disruption to occupiers down?

It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we are sealing.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Working on commercial sites near Ham

Rainfall across the South East, Ham included, is lower than in many parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Central London is about 64 miles from Ham. Business parks and retail centres are common around the capital’s motorway corridors. Firms with branches across the South East can use one contractor for every site.

Offices and shops close to stations such as Sandwich station, 1.7 miles north of Ham, tend to be busy all day, so sealant work is planned around opening hours. For tenants and agents on sites such as Birnham Farm Business Centre, 1.9 miles north-west of Ham, office fit-outs, reception joints and window perimeters are the usual sealant work.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Old mastic that tests positive for asbestos
  • A dripping trap, valve or pipe behind a fitting
  • Misted, cracked or failed glazing units (a glazier’s job)

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.

Where we work in Ham

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

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep abrasive pads and scrapers off resealed joints
  • Keep a record of which joints were resealed and when
  • Keep barriers up until the new sealant has cured
  • Check joints after other trades have worked nearby

We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records.

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. Resealing early keeps the problem in the sealant and out of the building.

Different surfaces, different methods

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. Access, such as scaffold already up, is agreed before the price is fixed.

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, and we install to the specification.
