Facade sealing near Hollow Street

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Render or concrete edges that have broken away
  • Water getting in through cracked render or porous masonry
  • Specialist high-level access methods

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.

Joints and surfaces we work on

  • Perimeter joints where frames meet the structure
  • Cladding panel joints
  • Window and door perimeters
  • Shopfront frames
  • Coping and flashing joints
  • Stone and brick facade joints

How we handle facade sealing in Hollow Street

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We plan for that and keep you updated. If you have unsightly perimeter sealant on a visible elevation and cladding panel joints that have opened up, we can put it right, whatever the surface. Most enquiries from Hollow Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In the countryside around places like Hollow Street, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or send photos by email and we’ll arrange a return visit.

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Never let anyone seal over old sealant
  • Note when each elevation was last resealed
  • Clear debris that holds water against joints
  • Plan facade sealing alongside redecoration

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.

Contractors’ notes for Hollow Street

Hollow Street sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Central London is about 56 miles from Hollow Street. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

School extensions, at buildings such as Chislet Church of England Primary School, usually run to the summer holidays, mastic included. When units on a site such as Chislet Business Park (to the south-west of Hollow Street) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. On a healthcare site such as St Martins Hospital, 5.1 miles to the south-west of Hollow Street, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Hollow Street is about 3 miles south-east of Herne Bay, in Kent. Anywhere in CT3, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Why it’s worth doing now in Hollow Street

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once, which is often the biggest saving. 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.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • A range of standard colours, depending on the product
  • Joints cleaned back to sound surfaces
  • Matching to RAL references, product permitting

Read what affects the cost or our accreditations and insurance.

Cost factors for facade joints

Your fixed quote is built from the real scope. It takes account of:

  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation
  • Access and working height
  • Phasing around occupants

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What we need to price the job

A few photographs plus some basic facts will normally do. Please tell us:

  • The site address and postcode
  • Your programme or deadline
  • The asbestos register, for older buildings
  • What the building is and how it’s used

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send details through our quote form with what you know.

General trades versus 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. For that reason, many FMs and contractors use a sealant specialist from the outset.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. If others near Hollow Street need work, visits can be combined. You will have a fixed quote before work starts.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

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

Ask for a quote

For a fixed quote, ring 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.

Hollow Street: questions and answers

Is a smaller place like Hollow Street outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you cover business parks and estates near Hollow Street, such as Chislet Business Park?

Yes. We cover Hollow Street and the area around it, including industrial estates, business parks and retail parks such as Chislet Business Park. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Can you work in cold or wet weather?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings.

Can you look at water coming in around a frame?

Yes. We check the sealant joints and report what we find before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
