Common questions from Puddledock clients

Can you work on a hospital site such as West Hill Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Could you schedule work at a campus like University of Greenwich for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

When is resealing likely to be due?

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.

What type of sealant goes on window perimeters?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.

Can staff carry on working while you’re here?

Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Facade sealing for commercial buildings in Puddledock

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. We work on shopfront frames, cladding panel joints and perimeter joints where frames meet the structure, and what we’re called in for most is cold air coming in at window perimeters and sealant pulling away from frames or panels. Facilities teams, main contractors and managing agents in Puddledock tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as Puddledock is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we’ll come back to it.

Facades, frames and programmes in Puddledock

At about 13 miles from central London, Puddledock is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Puddledock sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

Hotel extensions and refits, at places such as Rowhill Grange Hotel & Utopia Spa, 0.6 miles east of Puddledock, usually run between busy periods, so the sealing is squeezed into short windows. For contractors on a campus like University of Greenwich, 4.3 miles east of Puddledock, facade and perimeter sealing has to fit around students and term dates. Extensions at sites like West Hill Hospital, 2.5 miles north-east of Puddledock, usually sit beside working departments, and the mastic follows strict access rules.

Puddledock is about 1 mile north of Swanley, in Kent. Puddledock sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Kent, 931 places are covered, Puddledock among them. There’s a separate page for London, roughly 13 miles from Puddledock.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Note when each elevation was last resealed
  • Avoid patch repairs on failed facade joints
  • Keep sills, gutters and drainage paths clear
  • Share access with other external trades

Record the sealant type and date on the building file. Future work can then match the product and colour without guesswork.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading.

Cost factors for facade joints

We price every job individually. The main factors are:

  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first
  • The size and state of each joint
  • Working within restricted access windows

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Send us:

  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height
  • Specification clauses that apply
  • Where the site is, with the postcode

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

Honest limits

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints whose design needs changing by the specifier
  • Replacing glass or failed glazing units

If you’re not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer.

Where we work in Puddledock

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

Leave it or put it right?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. For buildings around smaller places like Puddledock, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

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 once you have the details.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Rural sites near Puddledock may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  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. The finished joints are checked with you.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
