Mastic sealing near Flackley Ash

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Mastic sealing in Flackley Ash, done properly

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. The enquiries we see most involve movement joints with sealant missing and draughts at frames across a block, across external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms. One point of contact handles commercial sealant work in Flackley Ash from the first photos to the final walk-round, for single jobs and planned programmes alike.

Rural conversions near places like Flackley Ash often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Flackley Ash may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

Your questions answered

Can you quote for a block close to Rye station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.

Is Flackley Ash too small for you to travel to?

Not at all. Flackley Ash is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Do you check for asbestos in old sealant?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.

Do you work for managing agents and housing associations?

Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.

Is mastic sealing guaranteed?

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

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Why deal with it now?

Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Halls, stores and units around places like Flackley Ash may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

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?

  • RAL and finish matching where the product range allows
  • Specification-led, product-correct work
  • Joints cleaned back to sound surfaces
  • Colour agreed before work starts

Signs you need mastic sealing in Flackley Ash

Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.

Site and facilities staff are often the first to spot these:

  • Patchy repairs in mismatched sealant
  • Failed external movement joints
  • Water getting in round frames after rain
  • Communal area joints that look neglected

Site managers at schools like Peasmarsh Church of England Primary School can fit frame mastic into the summer works.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • Are they CHAS accredited or on Constructionline?
  • Whether old or failed sealant will be cut out, not overlaid
  • Can the work be phased to keep areas open?

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Start inspections with the most exposed faces
  • Reduce knocks to communal area joints
  • Encourage occupiers to report problems at frames
  • Make mastic part of routine maintenance checks

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
