Construction mastic for commercial buildings in Paddock

Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Paddock, send drawings and the specification through our quote form. If you have new external sealant already peeling away and caulk cracking where joints are moving more than expected, we can put it right, on internal decorators’ caulk, cladding and panel joints and floor and skirting junctions alike. Searching for sealant specialists in Paddock? We’ve been sealing commercial buildings since 2005.

Sites around smaller places like Paddock can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Jobs in and around smaller places like Paddock are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  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.

Before we start on site

  • Share the asbestos register for older buildings
  • Point out any areas we must not close
  • Make sure the joints can be reached

Advice

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Cost factors for mastic packages

Your fixed quote is built from the real scope. It takes account of:

  • The product specified
  • Induction, permit and paperwork requirements
  • Any access equipment needed
  • Removal of failed or old sealant

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

Good information means a firmer quote. When you get in touch, include:

  • Anything awkward about access or site hours
  • The asbestos register, for older buildings
  • Specification clauses that apply
  • Drawings or a marked-up plan, if available

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.

Leave it or put it right?

Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple and a consistent finish. Around Paddock, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

A quote for mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

What you get with us

  • Matching to RAL references, product permitting
  • A Constructionline member, so easy to vet
  • Old sealant cut out, never sealed over
  • Public liability insurance in place

Paddock: questions and answers

Can the mastic package for our job in Paddock follow the site programme?

Yes, we work to the programme and the sequence the site sets. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is a hospital such as William Harvey Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What accreditations do you hold?

Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. Public liability insurance of five million pounds is in place too.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

What guarantee comes with a mastic package?

Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.

Is colour matching possible?

That depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

What we’re called out for in Paddock

Value-engineered products sometimes end up in the wrong joints. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.

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

  • Existing joints on a refurb that need cutting out and resealing
  • New external sealant already peeling away
  • Mastic snags holding up handover
  • Window and door perimeters that won’t pass inspection

With historic properties like Belmont House and Gardens, 3.8 miles north of Paddock, in the area, refurbishment work often meets old masonry that needs compatible sealants.

What to look for in a quote

  • What site paperwork they can supply
  • Do they follow the manufacturer’s priming guidance?
  • Will CSCS-carded applicators be on site?
  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

Sites and facades in and around Paddock

Paddock is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Paddock is about 45 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.

School extensions, at buildings such as Challock Primary School, typically run to the summer holidays, mastic included. Hospital estates such as William Harvey Hospital, 5.8 miles to the south-east of Paddock, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Paddock is about 5 miles north of Ashford, in Kent. We cover commercial sites throughout Paddock, whether it’s a single job or part of a planned programme. Our Kent coverage takes in 931 places, large and small. London is covered too, around 45 miles from Paddock.

  • Oversized gaps that need packing or adjustment by others

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

Surfaces we seal

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