How we handle mastic sealing in Faulkbourne

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on balcony and threshold joints, shopfronts below residential blocks and window and door perimeters on blocks, and what we’re called in for most is worn sealant at communal door frames and mastic failing across several blocks on an estate. A specialist sealant contractor works differently from a general builder: on jobs in Faulkbourne, preparation and product choice get the time they need.

Around smaller places like Faulkbourne, 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Faulkbourne, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  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.

Advice

Common questions from Faulkbourne clients

Is a smaller place like Faulkbourne outside your area?

Not at all. Faulkbourne is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

We manage a building near White Notley station. Can you help?

Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can you seal joints high up on a block?

We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.

How many days will you need on site?

That varies with the scale of the job, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.

Do you supply RAMS and insurance details?

We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.

When to call us in Faulkbourne

We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.

Clients usually get in touch after noticing something like this:

  • Failed external movement joints
  • Communal area joints that look neglected
  • Cracked, hardened mastic round windows on a block
  • Draughts at frames across a block

For owners of several units at places like Lanham Business Park (2.8 miles north of Faulkbourne), one programme can deal with frame and external mastic across the lot.

What to look for in a quote

  • How long is the guarantee, and what does it include?
  • Will CSCS-carded applicators be on site?
  • Are they CHAS accredited or on Constructionline?
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

What happens if it’s left?

Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Older rural buildings around Faulkbourne move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Why choose Mastic Doctor in Faulkbourne

  • Standard and matched colours in many product ranges
  • Workmanship guaranteed for 12 months
  • RAL and finish matching where the product range allows
  • CHAS accredited contractor

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Look at the sunniest and most exposed elevations first
  • Mention RAMS, insurance or CSCS requirements up front
  • Check the asbestos register before any old mastic is disturbed
  • Include mastic in your cyclical inspections

If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it unless told otherwise.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

For owners and agents in Faulkbourne

Rainfall across the South East, Faulkbourne included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Faulkbourne lies roughly 37 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.

Older community buildings, Parish Church of St Germanus among them, often have frames of mixed ages whose mastic varies. Blocks of flats and mixed-use buildings often cluster around stations such as White Notley station, 1.1 miles to the north of Faulkbourne, and their window and balcony mastic tends to age at the same rate across a building.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Materials that need asbestos testing before work
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Cost factors for mastic joints

Quotes vary with the job. It mainly depends on:

  • Working within restricted access windows
  • The total length or number of joints
  • Location, for remote and island sites
  • The size and state of each joint

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

The more we know, the firmer the quote. When you get in touch, include:

  • Where the site is, with the postcode

  • Whether the building will be occupied during the work
  • Specification clauses that apply
