About our mastic sealing in Stone Cross

Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. Site teams most often ask us about no planned programme for sealant and draughts at frames across a block, across external wall and movement joints, shopfronts below residential blocks and communal entrances and stairwells. Most enquiries from Stone Cross start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Around smaller places like Stone Cross, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Materials that need asbestos testing before work
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Failed window or door frames, which need a window contractor

If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.

Surfaces we seal

  • Balcony and threshold joints
  • External wall and movement joints
  • Shopfronts below residential blocks
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks
  • Communal entrances and stairwells

Do you need mastic sealing in Stone Cross?

UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

Things that usually lead to an enquiry:

  • Occupiers reporting cold air round windows
  • Estate-wide sealant that is simply worn out
  • Failed external movement joints
  • Worn sealant at communal door frames

Buildings close to stations like Ham Street station (to the south-west of Stone Cross) are often flats over shops, with frame mastic to keep sound.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Which product they’ll use, and why it suits the joint
  • How long is the guarantee, and what does it include?
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Stone Cross, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Share your working hours and any access restrictions
  • Make sure the joints can be reached

Advice

Why deal with it now?

Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. For buildings around smaller places like Stone Cross, 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. Resealing early avoids that.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why us?

  • Constructionline member
  • RAL and finish matching where the product range allows
  • Our applicators hold CSCS cards
  • One phone line for London, the South East and Scotland

Stone Cross: questions and answers

Can you quote for a block close to Ham Street station?

Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Is Stone Cross off your patch?

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 will plan the job to need as few trips as possible.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. The quote can be split however suits your budgeting.

What about access for upper-floor joints?

It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Is mastic sealing guaranteed?

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