Mastic sealing across Broad Street

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

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Leaks through the frame itself rather than the perimeter
  • Glazing that needs replacing
  • Substrate edges that need repairing first

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Surfaces we seal

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

Mastic sealing in Broad Street, done properly

Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints, and the usual reasons a site gets in touch are complaints coming in block by block and the same joint failures repeated across a portfolio. A single leaking joint is often how a building in Broad Street first comes to us: we look at the rest while we are there and tell you what we find.

Owners and agents with buildings around smaller places such as Broad Street tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Do you need mastic sealing in Broad Street?

Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.

Clients usually get in touch after noticing something like this:

  • Estate-wide sealant that is simply worn out
  • Open joints in brickwork or panels
  • Draught complaints from residents or tenants
  • No planned programme for sealant

Churches, halls and community buildings such as The Parish Church of St Nicholas are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • Will failed sealant be removed rather than covered?
  • Proof of insurance
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Common questions from Broad Street clients

Can you quote for a block close to Doleham station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Does the sea air around Broad Street change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Can you plan resealing across several buildings?

We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Do you guarantee the mastic work?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Maintenance after handover

For the best life from the joints:

  • Track which buildings were done and when
  • Share your contractor requirements early
  • Check the asbestos register before any old mastic is disturbed
  • Avoid piecemeal callouts where you can

Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.

One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

For owners and agents in Broad Street

With the shore within about 3 miles, Broad Street counts as a coastal location. On buildings near the shore, the side facing the weather usually needs its mastic renewed first. Broad Street is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.

With historic buildings such as Lamb House, 4.1 miles north-east of Broad Street, in the wider area, owners of older properties around Broad Street should expect mastic to need a product that suits old masonry. For agents with blocks near Doleham station, 1.8 miles west of Broad Street, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Broad Street is about 5 miles north-east of Hastings, in East Sussex.

Different surfaces, different methods

Communal areas

Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.

Planned maintenance

Planned resealing replaces emergency callouts and keeps budgets predictable.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • How accessible the joints are
  • How much there is to seal
  • Site requirements such as inductions and permits
  • Location, for remote and island sites

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Whether the building will be occupied during the work
  • The postcode of the building
  • When you need the work done
  • Drawings or a marked-up plan, if available

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send details through our quote form.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Broad Street are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Before we start on site

  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
