Locksgreen: questions and answers

Is a smaller place like Locksgreen outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Will you take on work at estates like Porchfield Business Park, close to Locksgreen?

Yes. Estates, retail parks and business parks around Locksgreen, Porchfield Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Can you clear a mastic snag list before handover?

Yes. Damaged, missed or untidy joints are stripped and done again properly, working to your handover date.

What happens if the weather stops external sealing?

Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.

How many days will you need on site?

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

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Construction mastic in Locksgreen

Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we are fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. If you have missed perimeter joints on a new elevation and oversized or tapered gaps around new frames, we can help, whatever the surface. Looking for mastic applicators who cover Locksgreen? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Around smaller places like Locksgreen, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Work we carry out in the Isle of Wight comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

How the quote is worked out

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

  • Which sealant the job calls for
  • Joint width, depth and condition
  • How much existing material needs removing
  • Location, for remote and island sites

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • When you need the work done
  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • Specification clauses that apply

For a fixed quote, call the office on 01277 525 020 or email drawings and photos. Our quote form is another easy route.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Specifying the product where the designer hasn’t
  • Oversized gaps that need packing or adjustment by others
  • Joints damaged after sign-off by following trades

If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.

Surfaces we seal

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

Construction mastic in Locksgreen: the local picture

Locksgreen is within about 2 miles of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Locksgreen 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, so we time external mastic for dry faces and agree it with the site team.

Extensions at sites like St Mary's Hospital, 3.1 miles to the east of Locksgreen, normally sit beside working departments, and the mastic follows strict access rules. For contractors refurbishing units at places like Porchfield Business Park (0.5 miles west of Locksgreen), the mastic covers cladding panels, roller-door and window perimeters.

Locksgreen is about 3 miles west of Newport, in the Isle of Wight. We send applicators to Locksgreen for mastic packages, handled exactly as we handle every other area. Locksgreen is one of 125 places in the Isle of Wight on our list. For work in that direction, see our Southampton page.

We cover the PO30 postcode districts. We also cover Porchfield (1 mile north-east), Newtown (1 mile west), Great Thorness (1 mile north-east), Forest Side (2 miles east) and Noke Common (3 miles east) for mastic packages. Nearby towns on our patch include Newport (3 miles east), Ryde (9 miles east), Cowes (4 miles north-east), Sandown (10 miles south-east), Shanklin (10 miles south-east) and Ventnor (11 miles south-east). Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you phone 01277 525 020 or email a schedule or drawings.

General trades versus a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Common problems we fix in Locksgreen

Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.

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

  • Old sealant on a refurbishment that needs stripping before new work
  • Missed perimeter joints on a new elevation
  • Mastic snags holding up handover
  • A mastic package split between trades with no clear owner

With historic properties like Swainston Manor, 1.7 miles to the south of Locksgreen, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Comparing quotes

  • How long is the guarantee, and what does it include?
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Locksgreen are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We price from the drawings, specification and programme you send.
  2. A fixed quote sets out the scope, the products and the sequence.
  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. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed
