Facade sealing for businesses in Green Cross

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

Why act early in Green Cross

Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Around Green Cross, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

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.

Why clients in Green Cross choose us

  • Sealing commercial buildings since 2005
  • Health and safety: CHAS accredited
  • Old sealant cut out, never sealed over
  • Fixed quotes based on photos, drawings or a visit

Facade sealing in Green Cross

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. Site teams most often ask us about damp patches beside frames after rain and failed sealant on precast panel joints, across stone and brick facade joints, window and door perimeters and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Green Cross, preparation and product choice get the time they need.

In the countryside around places like Green Cross, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Building and refurbishing in Green Cross

A number of hotels sit less than 2 miles from Green Cross. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. At about 38 miles from central London, Green Cross is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

Projects at schools like St John's CofE Aided Infant School work to term dates, so mastic is programmed tightly. New wings at hospitals like Haslemere and District Hospital (3.8 miles south-east of Green Cross) bring long runs of window and panel joints to seal.

Green Cross is about 5 miles south of Farnham, in Surrey. We cover Green Cross and the rest of Surrey, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 379 places across Surrey fall within our area, including Green Cross. We also cover Reading, some 24 miles away.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep pressure washers away from fresh sealant
  • Avoid patch repairs on failed facade joints
  • Clear debris that holds water against joints
  • Check the asbestos register before old mastic is disturbed

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

Use each reseal to correct the joint: 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.

What affects the price in Green Cross

We price every job individually. The main factors are:

  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses
  • The size and state of each joint
  • Site requirements such as inductions and permits

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

Before you send an enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Where the site is, with the postcode
  • Whether an asbestos survey exists
  • Any specification or named product
  • The type of building and who uses it

To get a fixed quote, ring 01277 525 020 or use the quote form, telling us the site location and the nature of the job. Our quote form is another easy route.

Common questions from Green Cross clients

Will you fit the mastic around our build programme in Green Cross?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is hospital work, at somewhere like Haslemere and District Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Is Green Cross in your area?

Yes. We cover Green Cross. For a quote, ring 01277 525 020 or send photos by email.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Green Cross are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

Building owners, agents and FMs in Green Cross

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

  • Providing access systems for the work
  • Joints whose design needs changing by the specifier

If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.
