How we handle construction mastic in Aaron's Hill

Mastic tends to be one of the final packages before handover, so it lands at exactly the point the programme is tightest. Mastic Doctor takes on mastic packages for main contractors and developers with projects in Aaron's Hill, following the trades through the building as rooms and elevations become ready. Most enquiries involve perimeter gaps outside the sealant’s range and internal caulk splitting as the building dries out, across floor and skirting junctions, sanitary and kitchen joints and window and door perimeters. Looking for mastic applicators who cover Aaron's Hill? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Conversions around smaller places like Aaron's Hill often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common questions from Aaron's Hill clients

Do you take on work at healthcare sites like Milford Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can work at a site such as University of Surrey - Manor Park Campus fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

What joints do you seal on a new build?

It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.

Can you quote from photographs?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Honest limits

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

  • Designing joint widths or choosing the specification (that sits with the designer)
  • Joints damaged after sign-off by following trades
  • Deciding which fire-stopping product a penetration needs

If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.

Joints and surfaces we work on

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

Surface by surface

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.

Window and door perimeters

A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting before sealing starts.

What we are called out for in Aaron's Hill

Wide, tapered or inconsistent gaps around frames are a common problem. 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.

Any of the following is a good reason to get the joints checked over:

  • A long mastic snag list close to completion
  • Perimeter gaps outside the sealant’s range
  • Sealant knocked or painted over by other trades
  • Internal caulk splitting as the building dries out

For a contractor working at a hospital such as Milford Hospital, 1.1 miles south of Aaron's Hill, perimeter and facade sealing is planned around patients and deliveries.

Comparing quotes

  • Will RAMS and insurance details be available?
  • Their plan for phasing and protecting the area
  • How joint depth will be controlled
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in Aaron's Hill is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.

  1. We start with the drawings, specification and programme.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Each area is sealed when it’s released.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work
  • Make sure the joints can be reached

Keeping the joints sound

To get the most from the new sealant:

  • Note which sealant went where at handover
  • Check frame gaps are within the sealant’s range before sealing
  • Share drawings and the specification as soon as possible
  • Allow flexibility for external sealing in damp or cold weather

A new structure shifts as it loses construction moisture. The right product in each joint copes with that. 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.

How the quote is worked out

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • Quantities, in metres or numbers

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

What we need to price the job

To price the job accurately, we need to understand the site. Send us:

  • Any specification or named product
  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours

Send us photographs, 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.
