Commercial sealant contractors in Strood

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Commercial sealant contractors in Strood, done properly

Most of the buildings we seal stay open while we’re there. Work is scheduled around the site hours and access windows you give us. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. The enquiries we see most involve movement joints packed with grit and debris and external beads that have gone brittle and cracked, across floor and threshold joints, external facade joints and movement joints in walls and floors. For commercial sealant work in Strood, you deal with one contact from quote to sign-off, whether it’s one building or several.

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

Smaller commercial landlords and businesses in a town like Strood often have a handful of sealant jobs that can go on one visit: a frontage, a staff washroom, a kitchen and a few window perimeters, for example. A single fixed quote covers everything on the list.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Shops, offices and hotels in and around Strood

At least three named trading, business or retail sites lie within about 3 miles of Strood. Each new occupier on a park like these tends to refit, from reception to staff kitchen. Strood sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

A business with units at Gun Lane Business Centre and Strood Retail Park needn’t use two contractors for its sealant. Premises within reach of Strood station, 1 mile east of Strood, often have busy frontages where joints are seen by everyone passing. Parks like Gun Lane Business Centre (to the north-east of Strood) see tenants come and go, and every move-in brings joints to seal.

Strood is about 3 miles north-west of Chatham, in Medway. Strood sits inside our coverage and the rest of Medway, with the same fixed quotes and 12-month guarantee as everywhere else. Strood is one of 54 places we cover in Medway. We also cover London, some 26 miles away.

Anyone looking for commercial sealant contractors in ME2, ME1 and ME3 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Buildings on Ash Road, Gun Lane and Pine Road are within our area. With the A2 and A226 nearby, Strood is easy to get to with materials and equipment. Nearby places we also cover include Rochester (1 mile east), Borstal (1 mile south), Cuxton (2 miles south-west), Lower Bush (2 miles south-west) and Upper Bush (2 miles south-west) for sealant joints. A short drive away, we cover Gillingham (4 miles east), Chatham (3 miles south-east), Rainham (6 miles east), Luton (3 miles south-east), Park Wood (6 miles south-east) and Lordswood (5 miles south-east). Strood is one of the busier places in Medway, and we take on sealant joints for its commercial and public buildings.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Report cracked or peeling sealant early
  • Put external and wet-area joints on a regular inspection round
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Have extract fans checked so wet areas dry out

Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. If that happens, ring 01277 525 020 or email a schedule or drawings and we will price putting it right.

Tenants and staff spot black or split sealant quickly, and it reflects on how the building is run. Planned replacement saves fielding the same complaint again and again.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Walls or slabs moving more than any sealant can take
  • Suspect materials that need testing and specialist removal
  • Broken glass or blown double-glazed units

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Surfaces we seal

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

Questions about Strood

Is Gun Lane Business Centre, near Strood, within your area?

Yes, sites like Gun Lane Business Centre are within our area, along with the rest of Strood. A few photographs and the unit address let us price the work.

Does a hotel in Strood need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Can areas stay open during the work?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Does commercial sealant work come with a guarantee?

Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Most work in Strood is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.

  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. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Agree which areas must stay open

Advice

How the quote is worked out

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

  • How much there is to seal
  • Whether old sealant has to be cut out first
  • Phasing around occupants
  • Joint width, depth and condition

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What we need to price the job

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

  • Asbestos survey details if the building is older
  • A wide shot and a close-up of the area
  • Your programme or deadline
  • Anything awkward about access or site hours

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email the details over if you’d rather talk the job through.

Why act early in Strood

Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. A failed joint is easier to put right before damp shows inside. After a leak, there’s drying, repairs and redecoration on top.

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Why appoint us

  • A range of standard colours, depending on the product
  • 12-month guarantee on workmanship
  • CHAS accredited
  • Commercial sealant work since 2005

When to bring in a specialist

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.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
