Mastic sealing for commercial buildings in Ifold

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you have occupiers reporting cold air round windows and the same joint failures repeated across a portfolio, we can put it right. Most enquiries from Ifold 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.

In and around smaller places like Ifold, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What we are called out for in Ifold

Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.

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

  • Mastic failing across several blocks on an estate
  • Repeated reactive repairs to the same buildings
  • Open joints in brickwork or panels
  • Worn sealant at communal door frames

Site managers at schools like Loxwood Primary School can fit frame mastic into the summer works.

Before you book anyone

  • What site paperwork they can supply
  • The named product and why it was chosen
  • Their approach to joint depth and backing
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

Quoting for work in Ifold

These are the things that shape the price:

  • The size and state of each joint
  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Your programme or deadline
  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • The site address and postcode

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Questions about Ifold

Is a smaller place like Ifold outside your area?

No. Places such as Ifold are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you price a mastic programme across our Ifold portfolio?

Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we’ll give a fixed quote.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is mastic sealing guaranteed?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Building owners, agents and FMs in Ifold

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

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.

Leave it or put it right?

Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Around Ifold, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What you get with us

  • Fully insured, including public liability cover
  • Commercial sealant work since 2005
  • A Constructionline member, so easy to vet
  • Fixed quotes based on photographs, drawings or a visit

Blocks and managed buildings in Ifold

Ifold is about 35 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Ifold 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.

If you’re responsible for a building such as St John the Baptist, frame and door mastic needs the same attention as any other property.
