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

Commercial mastic work in Goodnestone

Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Goodnestone, speak to us on 01277 525 020 or email us with the site addresses. We work on kitchen worktops and splashbacks, floor and threshold joints and window and door perimeters, and the usual reasons a site gets in touch are water staining near frames, panels or ceilings and frame sealant that has cracked, shrunk or pulled away. Looking for mastic applicators who cover Goodnestone? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

The most common commercial job in Goodnestone is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Work in smaller places such as Goodnestone tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

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

Building owners, agents and FMs in Goodnestone

We work for building owners and managing agents on everything from one building to a spread of sites around Goodnestone. One quote can cover more than one site, which keeps the paperwork simple.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Goodnestone can sit alongside others in a wider programme.

Aftercare for building managers

After handover, these steps help:

  • Keep barriers up until the new sealant has cured
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Report cracked or peeling sealant early
  • Brief cleaning contractors to avoid scourers and blades on sealant

Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just phone 01277 525 020 or email drawings and photos for a quote.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Goodnestone, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Before we start on site

  • Send your site hours and access windows
  • Flag any permit to work we’ll need
  • Have the specification and drawings to hand

Ask for a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or use the quote form.

Advice

Different surfaces, different methods

Fire-rated seals where specified

Not every penetration suits a sealant. Other products, such as collars, wraps and batts, are specified for different services, so we’ll flag it if the detail needs a different product.

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We will recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Induction, permit and paperwork requirements
  • Phasing around occupants
  • How much existing material needs removing
  • Distance, for remote addresses

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

Details that help us quote

However big the job, these details speed things up:

  • How the joints are reached, and at what height
  • Specification clauses that apply
  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Frontages, fit-outs and joints in Goodnestone

The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Central London is about 60 miles from Goodnestone. This part of the South East is dense with business parks and out-of-town offices. Multi-site occupiers here often want one sealant contractor across all their buildings.

Industrial estates such as Wingham Industrial Estate (to the north of Goodnestone) have offices, trade counters and welfare areas whose sealant ages like any other building’s. If you have premises on more than one site, say at Wingham Industrial Estate and Aylesham Industrial Estate, one contractor and one quote can cover both. Shops and cafés around stations like Adisham station, 1.5 miles west of Goodnestone, trade from early, so work is timed around them.

Questions about Goodnestone

Is Wingham Industrial Estate, near Goodnestone, within your area?

Yes, sites like Wingham Industrial Estate are within our area, along with the rest of Goodnestone. Send details of the unit and the work through our quote form for a quick quote.

Which site documents can you send us?

Send your site requirements with the enquiry. From you, we will need the asbestos information for older buildings and any site rules.

What about asbestos in old mastic?

On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility.

Can areas stay open during the work?

Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

What do you need from us to quote?

Send what you have, even a few photographs and rough lengths. Questions or a site visit follow where needed, and then a fixed quote for the agreed scope.
