Commercial sealant contractors for Dunsfold sites

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

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Commercial sealant contractors for commercial buildings in Dunsfold

Commercial occupiers rarely want a floor out of action for sealant work. Tell us your site hours and access windows and we’ll plan around them. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you have messy, uneven beads from earlier work that let the building down and expansion joints with the sealant torn out, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Dunsfold it comes down to the same thing: the right product in a properly prepared joint.

We price commercial jobs in Dunsfold from photos, drawings or a site visit, with the scope listed so everyone knows what’s included.

Business units in the countryside around places like Dunsfold are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Our workmanship is guaranteed for 12 months, in Dunsfold as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Common questions from Dunsfold clients

Is a smaller place like Dunsfold outside your area?

Not at all. Dunsfold is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you take on work at estates like Littlemead Industrial Estate, close to Dunsfold?

Yes. Estates, retail parks and business parks around Dunsfold, Littlemead Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you work directly for building managers?

Yes. A large share of our work comes through facilities managers, managing agents and landlords. We can work to your instruction process and site rules.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What guarantee do you give on resealing?

Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.

What about asbestos in old mastic?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients 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.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

What affects the price in Dunsfold

We price every job individually. The things that drive the figure:

  • The total length or number of joints
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • Joint width, depth and condition

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 quote when you’re ready.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • The type of building and who uses it
  • Specification clauses that apply
  • When you need the work done
  • A wide shot and a close-up of the area

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, ring 01277 525 020 or email a schedule or drawings.

Looking after the joints

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

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Check sealant as part of routine building inspections
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Note dates and locations of sealant work for future planning

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.

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.

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes part of a day on a small job and longer where several buildings or phases are involved, and our waste is bagged and taken away as we go. If others near Dunsfold need work, visits can be combined. A fixed quote is given before anything starts.

  1. You send photos, drawings or a list of the joints and areas involved, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

What we need from you

  • Explain the parking and delivery arrangements
  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed

  • Misted, cracked or failed glazing units (a glazier’s job)

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
