    WHAT IS JOINERY?

    Joinery is an all embracing term which refers to the lighter, finer and more ornamental timberwork of ahouse. Doors, windows, staircases, architraves, skirtings, archways and turnery are considered joinerywhereas heavier timberwork such as bearers, floors, walls and roof framing are carpenters work. Furniture and built in cupboards arecabinet makers work.

    WHAT ARE THE JOINERY ISSUES WHEN EXTENDING OR RAISING AN OLD HOUSE?

    There are a few design considerations that you need to take into account when renovating a traditional workers cottage that can have amajor bearing on the resale value of the venture and its costs. The original cottages were kit houses that used standard components.Generally all the windows were the same size and so were the doors. The design was composed using off the shelf items that wererepeated around the facade and internally. Later additions may have blurred this simplicity but the rules for a successful renovation are:

    Retain the original character of the house. This means preserving its original features and not over-restoring so that the authenticity is lost.

    Original victorian & federation houses had a very simple set of design rules. The internal and external joinery all maintained the samejoinery height. Picture rails would quickly highlight any discrepancy. The height of windows, french doors etc, all maintained the samejoinery height, with only the front door being slightly larger to signal its importance. (see diagram below)

    Renovating an old house calls for skill and attention to detail. There is usually a consistent theme to joinery so that moulding patterns andprofiles on doors and glazing patterns in windows are the same throughout. Dimensions of individual items may vary but their appearancewill generally be consistent. Variations may occur in the quality and extent of details in joinery items, as for example, from the morecomplex details found in major rooms to simpler forms used in lesser rooms but the theme will generally remain consistent. It is importantthat new additions or renovations respect the original details and operate within their perimeters.

    Look for the proportion and strength of traditionally constructed joinery. Although slight differences exist between imperial and metricjoinery sizes, external joinery doors should always be 40mm thick, window sashes 35mm thick and internal doors no less that 35mm thick.A great deal of joinery available in the market place is thinner and will not last as well in the harsh Australian climate. Insist on solid timberjoinery rather than veneered, engineered or hollow core doors as they can delaminate in our climate due to moisture movement. You also,of course, cant cut them down or fit them as is generally required in older homes.

    Remember that its a house, not a museum. You are just as much a part of its history as anyone else. Live in it, respect its pedigree and alterit sympathetically. The aim is for it to be in better shape for the changes youve made than it was when you arrived.

    WHY USE TIMBER JOINERY AT ALL?

    Timber joinery is often seen as requiring more maintenance than its aluminium counterpart but time has proven this to be incorrect. Whilepowdercoated aluminium will outlast the first paint coat on timber, it may not outlast the second repainting, particularly in salty environments.Whereas timber can always be sanded and repainted, powdercoating cannot be over-painted successfully and the entire joinery needs to bereplaced. Timber joinery simply performs better and enhances the integrity of the original architecture compared to its aluminium competition.

    DO WOODWORKERS RESTORE OLD JOINERY?

    Old doors meet a variety of misfortunes but can often be repaired to continue their life provided their basic structure is sound. Woodworkers arehappy to advise if a joinery item can be retrieved rather than replaced, as it is always preferable to conserve originals if theyve made it this far.Theoriginal door, though it may be badly worn or knocked about, has the patina of age and is part of the living history of your house. Blistered paint,missing mouldings and loose joints can all be rectified.Advice should be sought before paint stripping joinery in caustic baths. It will destroy the colour of the original cedar and usually loosens theglues that hold the joinery together.Beware however, that not all existing joinery may be original to your house. Many houses contain an accumu-lation of demolition yard finds that may confuse and bastardise the original style. These should be removed and a consistent style reinstatedthroughout the house. Replacement joinery should be sympathetic to the originals with careful attention paid to the proportions and style.

    HOW DO I KEEP COSTS UNDER CONTROL?

    The cost of joinery can easily be 15 to 20% of the total building budget and will regularly be the mostimportant single component of the renovation costs. A strategy for reducing its cost can therefore bevery rewarding. Once all the openings have been built you lose the flexibility to take advantage of market specials. It is generally better todo your shopping before the walls are built so that you do not get locked into having every piece custom made when standard off the shelfjoinery may have been a cheaper alternative. The use of second hand joinery can very occasionally be an option but remember that very

    few good buildings are demolished anymore and most are simply relocated. This means that very little good stock comes into the secondhand market and it is hard to get any quantities of matching joinery. You then have to deal with toxic lead, paint stripping, locks in the wronglocation and glass that does not meet current regulations. The cost of second hand joinery follows the cost of new joinery closely, usuallywith a $100 margin to attract the punters. When the cost of resizing, paint removal and repair is taken into account it is rarely economical.The next option is to investigate Woodworkers joinery orphanage for discounted excess stock that may meet your needs. You can shop online at www.woodworkersxs.com.au and there is a separate FAQ sheet devoted to how to select joinery from our joinery orphanage. Mostorphanage product is new and warranted and may be discounted 30% or more. As you rarely get more than a single item in any one size fromthe orphanage, it is often used to bring the overall costs down when used in conjunction with Woodworkers stock joinery range. Woodworkerscarry the industrys largest range of stock doors, windows, hardware and restoration supplies.There are separate brochures on all stockproducts which are commonly priced 20 to 30% cheaper than their custom made equivalents. Even when sizes are fixed, stock items may beable to be used in combination with custom joinery to reduce overall costs. Where no such options exist Woodworkers has a well deservedreputation for highly competitive pricing that has made us the industry leader in quality, custom made joinery.

    WHAT ABOUT WINDOW STYLES?

    Do not mix window styles - use all double hungs if the house pre-dates the mid 1920s and casements only if the original building had them.

    Casements were not used generally until after WW1 when the friction stay was invented but were not universally popular until post WW2when building restrictions reduced ceiling heights. Original double hungs had an extremity of frame size of approximately 1500 x 900, usuallyleaving 600mm between the top of the window and the ceiling. As ceiling heights fell in the 1930s and 1940s so did window heights, withthe style change to 1200 high casements. When raising a house, choose a window height that harmonises with the existing joinery and if itis possible to exactly match original sizes, so much the better.

    Original workers cottages were designed around constraints in joinery availability and glass sizes. Glass was transported from Sydney inpre-cut sizes and sashes were constructed to suit. This discipline in joinery sizes continued long after the size constraints of glass wereremoved and the Victorian preference for repetition and symmetry ensured that the facades of buildings were ordered and regimented.Avoid using odd size windows and always try to al ign joinery horizontally and vertically. Colonial double hung sashes were usually 1 or 2lights per sash.Casements used from 1930 to 1960 came in a wide variety of designs and were usually 4ft x 18 inch x 1 inch (1220mm x 464mm x35mm) in size with mostly obscure glass for privacy. They were hung on Whitco friction stays (which still exist) or hinged with telescopicstays. Woodworkers no longer use Whitcos for casement work as we believe the quality has deteriorated and superior stainless steel adjust-able stays are now preferred. Many of the original glasses used in casements are no longer available or legal within modern codes andparticular attention needs to be paid to glass availability and suitability when planning renovations.

    DO I NEED WINDOW HOODS?

    Yes. Original Queensland houses used window hoods on all external windows that were not protected by verandahs because hoodsprovided sun protection, privacy and made original joinery weathertight. While double hung windows have high natural water penetrationresistance, original designs of casements and sliders can leak during driving rain. While joinery can be manufactured with seals to eliminatewater penetration, seals will deteriorate over time and it is preferable if exposure is better controlled with hoods to provide a long termsolution.

    WHAT ABOUT INTERIOR DOORS?

    Pre-1930, interior doors were hung so that they obscured the view into a room until fully open. This enhanced privacy in an age of largerfamilies and domestic servants. Often doors will have been re-hung and sometimes even hung upside down to modernise when high waistdoors replaced Victorian 4 panel designs, or sheeted with ply to mimic flush doors. Woodworkers stock replicas of most internal door designscommonly encountered, or can manufacture to match where required. Perhaps the most common mistake in alterations is fitting out the newwork with hollow core doors in fake, wood grain finishes. Pressed hollow core doors may be much cheaper but always make a renovationlook as if it was done on a shoe string. As doors are so prominent, unsympathetic budget doors do nothing to enhance property value.

    DO I PAINT JOINERY OR CLEAR FINISH?

    Most original joinery dating from the colonial era was usually painted externally with oil based enamel and clearfinished internally withvarnish. Many National Trust properties (e.g. Newstead House) showcase this preference. Original varnish was manufactured from lacbeatle flakes mixed with metholated spirits, and Woodworkers still use this method to seal our glazing rebates prior to glass installation.Wherever joinery is exposed to full weather it remains preferable to fully paint the external face with linseed oil based enamels (not acrylics).This allows the exterior elevations to blend in with the original joinery so that the new work is not highlighted. Internally, the choice of paintor clear finish is yours, but remember that once painted you will not easily retrieve the colour of original cedar. Again oil based finishes arealways preferred for timber as they nourish the wood rather than suffocating it in plastic (with modern acrylic finishes). Refer our separateFAQ sheet on finishing for our recommendations for suitable clear products. If you choose to traditionally paint joinery, your choice of oilbased primer is crucial. Most paint available is too oily, and will take many days or weeks to dry sufficiently to allow the work to be smoothsanded for subsequent coats. What is required is a fast dry (e.g. one hour) oil based primer that will powder quickly when sanded withoutclogging the sandpaper, & produce a smooth substrate for gloss enamel top coats. Woodworkers sales staff can advise on suitable primerproducts that will produce a fast, smooth finish.
