Construction mastic for Hazel Street sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Why deal with it now?

Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go and saves applicators coming back again and again. Snagging can be priced as a separate stage. Around Hazel Street, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Pricing mastic packages depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Why choose Mastic Doctor in Hazel Street

  • Public liability insurance in place
  • Over 20 years of commercial sealing
  • Clear, fixed quotes
  • Colours confirmed for the specified product

Construction mastic in Hazel Street

Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. Our aim is joints that pass at the first inspection, area by area through the programme. The enquiries we see most involve external joints sealed in damp or cold conditions that are now failing and internal caulk splitting as the building dries out, across brick and block movement joints, floor and skirting junctions and internal decorators’ caulk. A specialist sealant contractor works differently from a general builder: in Hazel Street, that means joint design, primers and backing rod as standard.

In the countryside around places like Hazel Street, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we will come back to it.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Deciding which fire-stopping product a penetration needs
  • Specifying the product where the designer hasn’t
  • Damage to finishes by other trades after we have sealed

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly before you book.

What we seal

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

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Your questions answered

Is Hazel Street off your patch?

No. Places such as Hazel Street are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you take on a job at a hospital such as Tunbridge Wells Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

How do you work with the site programme?

We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready.

What accreditations do you hold?

CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Quoting for work in Hazel Street

We price every job individually. The things that drive the figure:

  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Quantities, in metres or numbers

We don’t publish prices, since every building and every scope is different. Call for a quote.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • When you need the work done
  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height
  • The site address and postcode

To get a fixed quote, give us a call on 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. You can also send details through our quote form.

New build and refits around Hazel Street

Hazel Street lies roughly 34 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Hazel Street sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

With historic properties like Scotney Castle, 2.7 miles to the south of Hazel Street, in the area, refurbishment work often meets old masonry that needs compatible sealants. When a school such as Horsmonden Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Hospital estates such as Tunbridge Wells Hospital (5.1 miles west of Hazel Street) 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.

Hazel Street is about 7 miles east of Royal Tunbridge Wells, in Kent. Any commercial site in Hazel Street is covered, for single jobs and planned programmes alike. Hazel Street is one of 931 places in Kent on our list for mastic packages. There’s a separate page for Brighton, about 32 miles away.

If you need construction mastic in TN12, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes a day or two on a small fit-out and several weeks on a large multi-storey package. Rural sites near Hazel Street may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Preparing the site

  • Point out parking and an unloading spot
  • Agree which areas must stay open
  • Warn occupants and staff about the work
