Construction mastic in Henley Street

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

About our construction mastic in Henley Street

Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. We work on cladding and panel joints, internal decorators’ caulk and brick and block movement joints, and the failures we’re asked to look at most are existing joints on a refurb that need cutting out and resealing and different trades sealing to different standards. Searching for sealant specialists in Henley Street? We’ve been sealing commercial buildings since 2005.

Sites around smaller places like Henley Street can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What happens if it’s left?

Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. If the frame is life-expired, we’ll tell you. For buildings around smaller places like Henley Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Building and refurbishing in Henley Street

Henley Street sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. At about 23 miles from central London, Henley Street is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

With historic properties like Cobham College, 0.8 miles to the north of Henley Street, in the area, refurbishment work often meets old masonry that needs compatible sealants. Recladding or extending a unit at a site like Bowes Industrial Centre, 2.2 miles south-west of Henley Street, brings panel joints and frame perimeters into the programme. New wings at hospitals like Gravesham Community Hospital, 4.7 miles to the north of Henley Street, bring long runs of window and panel joints to seal.

Henley Street is about 4 miles south of Gravesend, in Kent. Our applicators travel to Henley Street for work on mastic packages, handled exactly as we handle every other area. We work across 931 places in Kent, large and small. Sites around London have their own page, about 23 miles away.

If you need construction mastic in DA13, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. We also cover Luddesdown (1 mile south), Gold Street (1 mile north-west), Sole Street (1 mile north-west), Round Street (1 mile north-west) and Foxendown (1 mile south-west) for mastic packages. Further afield, our area takes in Maidstone (10 miles south-east), Sittingbourne (15 miles east), Dartford (9 miles north-west), Sevenoaks (11 miles south-west), Gravesend (4 miles north) and Tonbridge (13 miles south).

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Henley Street, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First we take quantities off the drawings and read through the specification.
  2. You receive a fixed quote listing scope, products and phasing.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

What we need from you

  • Tell us which areas need to stay in use
  • Let building users know which areas are affected
  • Point out parking and an unloading spot

Getting a fixed quote

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.

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Access and working height
  • Removal of failed or old sealant
  • The total length or number of joints
  • Which sealant the job calls for

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Where the site is, with the postcode
  • Whether an asbestos survey exists
  • Clear photos of the problem areas
  • What the building is and how it’s used

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Frames fitted out of tolerance
  • Joints damaged after sign-off by following trades
  • Designing joint widths or choosing the specification (that sits with the designer)

If you are not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

What we seal

  • Floor and skirting junctions
  • Internal decorators’ caulk
  • Brick and block movement joints
  • Window and door perimeters
  • Cladding and panel joints
  • Sanitary and kitchen joints

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What the job involves on each surface

Kitchens and utility areas

On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.

Snagging before handover

Snags normally come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.

Your questions answered

Is Henley Street too far out for you?

No. Places such as Henley Street are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Would you work within a site like Gravesham Community Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

How do you work with the site programme?

We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Can you work while the building is occupied?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

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.
