Mastic sealing near Braywoodside

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

Mastic sealing in Braywoodside, done properly

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. The enquiries we see most involve repeated reactive repairs to the same buildings and worn sealant at communal door frames, across external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints. Most enquiries from Braywoodside start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

For owners with a single building near Braywoodside, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What sets the cost

We price every job individually. The things that drive the figure:

  • Distance, for remote addresses
  • The site’s rules and procedures
  • Whether old sealant has to be cut out first
  • Phasing around occupants

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Sending details for a quote

There’s no need for a formal survey. These details are enough to start:

  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area
  • Your programme or deadline
  • Whether the building will be occupied during the work

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or email the details over.

Should maintenance staff do it?

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Smaller jobs around Braywoodside can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

What we need from you

  • Warn occupants and staff about the work
  • Confirm the product named in the specification
  • Let us know about inductions and permits

Request a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or use the quote form.

Why act early in Braywoodside

Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. For buildings around smaller places like Braywoodside, 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. Renewing joints in good time avoids the problem.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why choose Mastic Doctor in Braywoodside

  • Health and safety: CHAS accredited

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Masonry that has broken away beside the joint
  • Materials that need asbestos testing before work
  • Water coming in from the roof or rainwater goods

If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think.

Joints and surfaces we work on

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

Maintenance after handover

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

  • Look at the sunniest and most exposed elevations first
  • Ask residents or tenants to report leaks and draughts early
  • Protect low-level joints in entrances
  • Include mastic in your cyclical inspections

Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.

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.

For owners and agents in Braywoodside

Central London is about 28 miles from Braywoodside. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Braywoodside is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

With historic buildings such as Dorney Court (to the north-east of Braywoodside) in the wider area, owners of older properties around Braywoodside should expect mastic to need a product that suits old masonry. If you own or manage units on a site such as Grove Business Park, 1.9 miles north-west of Braywoodside, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Site managers at schools like Holyport College can fit frame mastic into the summer works.

Braywoodside is about 3 miles south of Maidenhead, in Windsor and Maidenhead.

Braywoodside: questions and answers

Do you work for managing agents with blocks near Maidenhead 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 Braywoodside too small for you to travel to?

Not at all. Braywoodside is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do you check for asbestos in old sealant?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

Can you seal joints high up on a block?

Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.

Do you do block-wide mastic programmes?

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

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
