Construction mastic in Forest Corner

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Signs you need construction mastic in Forest Corner

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.

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

  • External joints sealed in damp or cold conditions that are now failing
  • A mastic package split between trades with no clear owner
  • Frame gaps too wide for sealant alone
  • Sanitary sealant damaged by following trades

Older buildings in the area around Forest Corner, such as Avon Tyrrell House, 3.6 miles to the south of Forest Corner, need care when sealed: the product has to suit soft or historic materials.

Before you book anyone

  • Proof of insurance
  • What the guarantee covers, and for how long
  • Are they CHAS accredited or on Constructionline?
  • How the existing material will be dealt with

Our contractor checklist

How we handle construction mastic in Forest Corner

Buyers, tenants and clients notice sealant lines long before they notice the structure. 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. The enquiries we see most involve mastic snags holding up handover and old sealant on a refurbishment that needs stripping before new work, on brick and block movement joints, sanitary and kitchen joints and window and door perimeters. Searching for sealant specialists in Forest Corner? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

For a site near Forest Corner, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we’ll come back to it.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Building and refurbishing in Forest Corner

Several hotels sit less than 2 miles from Forest Corner. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Rainfall across the South East, Forest Corner included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

For a contractor working at a hospital such as St Leonard's Hospital (5.3 miles south-west of Forest Corner), perimeter and facade sealing is planned around patients and deliveries. When a school such as Poulner Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.

Forest Corner is about 1 mile east of Ringwood, in Hampshire. Across the BH24 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 723 places in Hampshire. Southampton is covered too, around 16 miles from Forest Corner.

We cover the BH24 postcode districts. If your site is on Burcombe Lane, St Aubyns Lane and Picket Hill or close by, we can quote for mastic packages. Close to Forest Corner, our area also takes in Foulford (1 mile south-east), Shobley (1 mile north-east), Hangersley (1 mile north-west), Poulner (1 mile west) and Hightown (1 mile south-west).

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Forest Corner may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We price from the drawings, specification and programme you send.
  2. You receive a fixed quote listing scope, products and phasing.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it 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. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Advice

Surface by surface

Window and door perimeters

Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team.

Internal decorators’ caulk

Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.

Questions we are asked in Forest Corner

Would you work within a site like St Leonard's Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Forest Corner too far out for you?

No. Places such as Forest Corner are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Can the sealant be colour-matched?

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.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or use the quote form. Include photographs or drawings if you have them.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Oversized gaps that need packing or adjustment by others
  • Approving fire stopping as compliant
  • Damage to finishes by other trades after we’ve sealed

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly.

What we seal

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

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
