Mastic sealing for Fawkham Green sites

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

Mastic sealing in Fawkham Green, done properly

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on communal kitchens and washrooms, balcony and threshold joints and shopfronts below residential blocks, and the failures we’re asked to look at most are communal area joints that look neglected and cracked, hardened mastic round windows on a block. Most enquiries from Fawkham Green 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 buildings around smaller places like Fawkham Green, we group work so one trip covers it. Photos of each elevation help us quote accurately.

A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Commercial clients in Fawkham Green

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Substrate edges that need repairing first
  • Failed window or door frames, which need a window contractor
  • Broken glass or failed sealed units

If you are not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer before you book.

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

Questions we are asked in Fawkham Green

Do you work for managing agents with blocks near Longfield station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Do you cover business parks and estates near Fawkham Green, such as Heaver Farm Trading Estate?

Yes, sites like Heaver Farm Trading Estate are within our area, along with the rest of Fawkham Green. A few photos and the unit address let us price the work.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Do you work in Fawkham Green?

Yes. Sites across Fawkham Green are covered, with one number for every area we cover.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Why act early in Fawkham Green

Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Around Fawkham Green, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why choose Mastic Doctor in Fawkham Green

  • CSCS-carded applicators

What affects the price in Fawkham Green

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • How accessible the joints are
  • Phasing around occupants

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Any dates the work must fit around
  • Clear photos of the problem areas
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If others near Fawkham Green need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we look at the mastic on each building and note what needs replacing.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Getting the site ready

  • Let us know about inductions and permits
  • Send any specification or drawings in advance
  • For older buildings, check the asbestos register before work

Ask for a quote

Block-wide mastic in Fawkham Green

Fawkham Green is about 19 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. The South East is one of the drier parts of the UK. 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.

Trustees of buildings like Parish Church of Saint Peter and Saint Paul can bring frame and external mastic into a planned maintenance list. Landlords with units on estates such as Heaver Farm Trading Estate, 0.7 miles south-east of Fawkham Green, can bring frame, door and external mastic across several units into one programme. Historic properties like Lullingstone Castle (to the west of Fawkham Green) show the age of some local stock, where frame mastic must suit soft brick or stone.
