What we are called out for in Martins Heron

Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.

Clients usually get in touch after noticing one or more of the following:

  • Cracks opening in caulked internal joints
  • Sanitary sealant damaged by following trades
  • Perimeter gaps outside the sealant’s range
  • External joints sealed in damp or cold conditions that are now failing

On a campus such as Imperial College Silwood Park Campus, 3.3 miles to the east of Martins Heron, new teaching buildings and residences are usually built and refurbished around the academic year.

  • Whether their applicators hold CSCS cards
  • Their public liability cover
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Construction mastic in Martins Heron

Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place. If you’re dealing with sanitary sealant damaged by following trades and failed sealant in an existing building being refurbished, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Martins Heron it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

On a small site around Martins Heron, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Construction mastic around Martins Heron: points for this area

Martins Heron sits in or beside Bracknell, a twentieth-century planned town. Regeneration of planned-town buildings brings recladding and replacement windows, each with joints to seal. Several hotels sit less than 2 miles from Martins Heron. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

Hotels like The Royal Foresters Hotel, 0.7 miles east of Martins Heron, rarely close for long, so refurbishment mastic is phased floor by floor. Extensions at sites like Heatherwood Hospital, 1.6 miles east of Martins Heron, normally sit beside working departments, and the mastic follows strict access rules.

Common questions from Martins Heron clients

Is a smaller place like Martins Heron outside your area?

Not at all. Martins Heron is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Is a hospital such as Heatherwood Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Looking after the joints

To get the most from the new sealant:

  • Use the product the specification names
  • Allow flexibility for external sealing in damp or cold weather
  • Brief the final clean team to avoid blades near sealant
  • Note which sealant went where at handover

A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.

External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go. Work in places the size of Martins Heron is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.

Getting the site ready

  • Warn occupants and staff about the work
  • Agree which areas must stay open

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Oversized gaps that need packing or adjustment by others
  • Approving fire stopping as compliant
  • Damage to finishes by other trades after we have sealed

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

Joints and surfaces we work on

  • Brick and block movement joints
  • Window and door perimeters
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Sanitary and kitchen joints
  • Floor and skirting junctions

Surface by surface

Snagging before handover

Snagging is often the final mastic stage. Snags are cleared room by room and damaged joints are redone rather than patched.

Internal decorators’ caulk

Caulking is often done in a hurry by whoever’s on site. Done properly, it saves decorators time and gives a clean line and reduces snags.
