About our facade sealing in Farncombe

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. Most enquiries involve facade joints cracked through the middle and cold air coming in at window perimeters, on coping and flashing joints, shopfront frames and stone and brick facade joints. A specialist sealant contractor works differently from a general builder: on jobs in Farncombe, preparation and product choice get the time they need.

Conversions around smaller places like Farncombe often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Render or concrete edges that have broken away
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints whose design needs changing by the specifier

If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think.

Where we work in Farncombe

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

Why it’s worth doing now in Farncombe

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • Specification-led, product-correct work
  • Over 20 years of commercial sealing
  • Failed material removed, not covered up
  • Coloured sealants to suit the setting, where available

When to bring in a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements
  • Removal of failed or old sealant
  • Travel to remote or island sites

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Your programme or deadline
  • Whether the building will be occupied during the work
  • Specification clauses that apply
  • How the joints are reached, and at what height

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email drawings and photos.

Common questions from Farncombe clients

Does your area include sites such as Godalming Business Centre, near Farncombe?

Yes. We cover Farncombe and the area around it, including industrial estates, business parks and retail parks such as Godalming Business Centre. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is Farncombe too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and the quote will reflect it.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

How long do sealant joints 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.

What will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Is old mastic on our building likely to contain asbestos?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.

New build and refits around Farncombe

A 2-mile radius around Farncombe takes in several hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. 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 the external programme keeps a little slack.

New units and refits on sites such as Godalming Business Centre (to the south of Farncombe) need their panel and perimeter joints sealed to the specification. On a healthcare site such as Milford Hospital, 2.2 miles south of Farncombe, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Several jobs near Farncombe can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out 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

  • Arrange parking or a loading space
  • Let building users know which areas are affected
  • Make sure the joints can be reached

Related advice

What we’re called out for in Farncombe

When the sealant tears down its centre, it has normally been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Things that normally lead to an enquiry:

  • Draughts around frames and panels
  • Damp patches beside frames after rain
  • Weathered facade joints that have lost their grip
  • Facade joints cracked through the middle

For a contractor at a hotel such as Godalming Hotel (less than half a mile south-east of Farncombe), the mastic often has to be finished before a reopening date.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • Proof of insurance
  • The named product and why it was chosen
  • Are they CHAS accredited or on Constructionline?
