Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Construction mastic in Standford

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. For construction mastic on a scheme in Standford, send drawings through our quote form, or phone or email us to talk it through. We work on window and door perimeters, floor and skirting junctions and brick and block movement joints, and the failures we are asked to look at most are new external sealant already peeling away and frame perimeters left unsealed or poorly sealed. For commercial sealant work in Standford, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Conversions of older rural buildings near smaller places such as Standford bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Surface by surface

Internal decorators’ caulk

Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move.

Window and door perimeters

Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. The specification decides which.

What affects the price in Standford

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height
  • The size and state of each joint
  • Working within restricted access windows

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • Anything awkward about access or site hours
  • When you need the work done
  • Any specification or named product
  • A wide shot and a close-up of the area

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or email a schedule or drawings.

Common problems we fix in Standford

On construction sites, joints normally fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.

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

  • A mastic package split between trades with no clear owner
  • Sealant knocked or painted over by other trades
  • Mastic snags holding up handover
  • Existing joints on a refurb that need cutting out and resealing

For contractors refurbishing units at places like Passfield Industrial Estate, which lies south-east of Standford, the mastic covers cladding panels, roller-door and window perimeters.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Standford can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We walk the site or review drawings to understand the package.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

Before we start on site

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email us to discuss it first.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Record the products used in the O&M file
  • Ask cleaners to use soft cloths around fresh sealant
  • Use the product the specification names
  • Bring the mastic contractor in after the last trades are through

Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. We can advise if a joint needs a different product.

In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.

Facades, frames and programmes in Standford

Standford lies roughly 42 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

Hospital estates such as Chase Hospital, 1.1 miles west of Standford, 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. For contractors at a school such as Weyford Nursery and Primary School, sealing has to be finished before term starts.

Standford is about 7 miles south-east of Alton, in Hampshire. Anywhere in GU35, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 723 places in Hampshire. Our Portsmouth page has more on work in that area.

Postcode districts covered here: GU35. Buildings on Robin Hood Gardens, Standford Lane and Tulls Lane are within our area for mastic packages. Just outside Standford, we also work in Hollywater (1 mile south-west), Deadwater (1 mile north-west), Lindford (1 mile north-west), Headley (1 mile north-east) and Bordon (1 mile north-west).

Work for main contractors and building owners

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Standford can form part of a wider programme across Hampshire.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Your questions answered

Would you work within a site like Chase Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Standford outside your area?

No. Places such as Standford are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you install fire-rated sealant as part of a package?

It can be part of the package where specified. Tell us what records you need and we’ll confirm with the quote.

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.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Can you seal external joints in wet or cold weather?

Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems.
