Sealant on show in Hollow Street’s commercial buildings

Hollow Street has two named business or industrial parks inside a 3-mile radius. Each new occupier on a park like these tends to refit, from reception to staff kitchen. Hollow Street is about 56 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site.

On a business park such as Chislet Business Park, 1 mile south-west of Hollow Street, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. Premises within reach of Sturry station, 3.6 miles to the south-west of Hollow Street, often have busy frontages where joints are seen by everyone passing. Occupiers with premises at both Chislet Business Park and Canterbury Industrial Park could have the sealant at each handled under one quote.

Hollow Street is about 3 miles south-east of Herne Bay, in Kent. Any commercial site in Hollow Street is covered. We work across 931 places in Kent, large and small. London is covered too, some 56 miles away.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Note dates and locations of sealant work for future planning
  • On pre-2000 buildings, share the asbestos information before work starts
  • Keep barriers up until the new sealant has cured
  • Make sure ventilation in wet areas is switched on and working

Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.

From enquiry to sign-off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area.

  2. Next comes a diagnosis and a fixed quote.
  3. Site hours, access windows and the order of areas are agreed before we start.

Questions we are asked in Hollow Street

Can you supply sealant in our brand colour for a site in Hollow Street?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.

Is Hollow Street too small for you to travel to?

Not at all. Hollow Street is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

What site paperwork can you provide?

Let us know your requirements when you ask for a price, and we will confirm the RAMS, insurance and CSCS details with the quote. For older buildings we’ll ask for the asbestos register, plus your site induction rules.

Why deal with it now?

Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme. Halls, stores and units around places like Hollow Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

What the job involves on each surface

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, and a hygienic or food-safe sealant is used where food contact is possible.

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. Fire-stopping design and sign-off sit with the designer, fire engineer or building control; we install what’s specified.

Cost factors for sealant joints

We price every job individually. The main factors are:

  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • Quantities, in metres or numbers

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Clear photographs of the problem areas
  • Whether an asbestos survey exists
  • The site address and postcode
  • How the joints are reached, and at what height

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or email us.
