Mastic sealing for Puddledock sites

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

Mastic sealing in Puddledock, done properly

Managing agents and housing associations normally need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks, and what we are called in for most is draught complaints from residents or tenants and failed external movement joints. Whoever orders the work in Puddledock, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Owners and agents with buildings around smaller places such as Puddledock tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What affects the price in Puddledock

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

  • How much there is to seal
  • Joint width, depth and condition
  • Which sealant the job calls for
  • Site requirements such as inductions and permits

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

Before you send an enquiry

However big the job, these details speed things up:

  • The product your specification calls for
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back
  • Whether an asbestos survey exists

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

Signs you need mastic sealing in Puddledock

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.

Clients normally get in touch after noticing something like this:

  • Occupiers reporting cold air round windows
  • Communal area joints that look neglected
  • Damp patches beside frames
  • Patchy repairs in mismatched sealant

Buildings close to stations like Swanley station (to the south of Puddledock) are often flats over shops, with frame mastic to keep sound.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • How joint depth will be controlled
  • How the joint faces will be prepared and primed
  • Their plan for phasing and protecting the area

Our contractor checklist

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Start inspections with the most exposed faces
  • Ask residents or tenants to report leaks and draughts early
  • Protect low-level joints in entrances
  • Log resealing dates block by block

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.

Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Your questions answered

Can work in a care setting near Puddledock go ahead while residents are there?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.

Is Puddledock too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you guarantee the mastic work?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

Can you plan resealing across several buildings?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

How do I request a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Looking after buildings in and around Puddledock

Three care or nursing homes sit less than 2 miles from Puddledock. Care home owners need frame and external mastic kept sound without unsettling residents. Puddledock is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

Owners of student blocks near University of Greenwich (to the east of Puddledock) can schedule frame and external mastic for the summer vacation. For a school such as Hextable Primary School, perimeter mastic on windows and doors is a holiday job.

What happens if it’s left?

Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. One visit to deal with every failing joint makes more sense than several trips to a place like Puddledock, rather than one at a time. Send photos of each area and we will quote for the lot.

Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.
