Facade sealing for businesses in Green Street

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

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. If others near Green Street need work, visits can be combined. You will have a fixed quote before work starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Send any specification or drawings in advance
  • Make sure the joints can be reached
  • Let us know about inductions and permits

Advice

Facade sealing in Green Street, done properly

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Most enquiries involve weathered joints at frame-to-structure perimeters and leaks at window and door perimeters, across shopfront frames, coping and flashing joints and stone and brick facade joints. Looking for mastic applicators who cover Green Street? We’ve been sealing commercial buildings since 2005.

Around smaller places like Green Street, 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.

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.

Questions about Green Street

Could you schedule work at a campus like Writtle University College Cow Watering Campus for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is Green Street too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Can you find out why a window is leaking?

Yes. We check the sealant joints and report what we find. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Movement beyond what any sealant can handle
  • Providing access systems for the work
  • Work on the window or framing system itself

If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think.

Where we work in Green Street

  • Window and door perimeters
  • Cladding panel joints
  • Stone and brick facade joints
  • Coping and flashing joints
  • Shopfront frames
  • Perimeter joints where frames meet the structure

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Inspect facade joints on a regular cycle
  • Note when each elevation was last resealed
  • Combine resealing with other works that need access
  • Ask about asbestos in pre-2000 mastic

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Why act early in Green Street

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. For buildings around smaller places like Green Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Mastic packages on Green Street sites

Green Street is about 23 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Green Street 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.

Building work at universities like Writtle University College Cow Watering Campus, 4.8 miles north-east of Green Street, is often timed for the summer, mastic included. With historic properties like Ingatestone Hall, 1.9 miles to the south-east of Green Street, in the area, refurbishment work often meets old masonry that needs compatible sealants. School extensions, at buildings such as Ingatestone Infant School, usually run to the summer holidays, mastic included.

Green Street is about 4 miles north-east of Brentwood, in Essex. We send applicators to Green Street for facade joints. Our Essex coverage takes in 644 places, large and small. Our London page has more on work in that area, about 23 miles away.

Commercial sites across CM4 are covered. Nearby places we also cover include Beggar Hill (1 mile north), Fryerning (1 mile east), Swallows Cross (1 mile south-west), Mill Green (1 mile north-east) and Ingatestone (1 mile east) for facade joints.

What sets the cost

Each job is priced on its own details. The main factors are:

  • How accessible the joints are
  • Distance, for remote addresses
  • The total length or number of joints
  • Whether the work must be split into stages

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Drawings or a marked-up plan, if available
  • The type of building and who uses it
  • Where the site is, with the postcode
  • Any specification or named product

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
