Construction mastic for commercial buildings in Margery

Since 2005 we have worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Margery, send drawings and the specification through our quote form. If you’re dealing with bath and shower joints scraped during the final clean and window and door perimeters that won’t pass inspection, we can put it right, on brick and block movement joints, window and door perimeters and cladding and panel joints alike. Whoever orders the work in Margery, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Margery, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For work around Margery, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. The sequence is agreed with the site manager.
  4. Plots or floors are sealed as they’re handed over.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

What we need from you

  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use
  • Send your site hours and access windows

Quotes

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Contractors’ notes for Margery

Central London is about 17 miles from Margery. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Margery included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

Hospital estates such as East Surrey Hospital (to the south-east of Margery) 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. Units on estates such as Chesterfield Business Park (1.7 miles south-west of Margery) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Further education sites such as Reigate College (to the south of Margery) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Margery is about 2 miles north of Reigate, in Surrey. Anywhere in KT20, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Margery is one of 379 places in Surrey on our list. There’s a separate page for London, roughly 17 miles from Margery.

If you need construction mastic in KT20, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include Manor Lane, Margery Lane and Mint Lane, and sites on any of them can send details for a fixed quote. Just outside Margery, we also work in Mogador (1 mile west), Lower Kingswood (1 mile north-west), Reigate (2 miles south), Kingswood (2 miles north) and Walton on the Hill (2 miles north-west). A short drive away, we cover Epsom (6 miles north-west), Horley (6 miles south), Ewell (7 miles north), Walton-on-Thames (12 miles north-west), Caterham (5 miles east) and Dorking (6 miles west).

Why deal with it now?

A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we’ll say so. Halls, stores and units around places like Margery may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • One number for every site we cover
  • Over 20 years of commercial sealing
  • Constructionline member

How the quote is worked out

What shapes the price:

  • The size and state of each joint
  • How accessible the joints are
  • Working within restricted access windows
  • Site requirements such as inductions and permits

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Anything awkward about access or site hours
  • Clear photos of the problem areas
  • Whether an asbestos survey exists
  • Rough lengths or quantities, or drawings if you have them

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

What the job involves on each surface

External facade and movement joints

Many facade substrates need a primer before sealing. We prime where the manufacturer specifies.

Window and door perimeters

Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification and set the depth with backing where needed.

Work for main contractors and building owners

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.

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

When something else is needed

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

  • Rework caused by others damaging completed areas
  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)

If you are not sure, just call 01277 525 020 or email us and we’ll give you a straight answer.

Surfaces we seal

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