All Tech Consulting Home Inspections

While we inspect houses of all ages, 

Heritage Homes are our Specialty!


All houses have stories to tell and heritage homes speak volumes.  It takes a certain insight to see into the past. It is written in the structure, carved in the beams and displayed in the architecture of the home.



To take place in Kingston and Ottawa. Due to Covid, the Seminars have been moved to October 2021, with exact dates to be announced by late Summer.

This course was developed by Cam Allen for use as a training seminar for the Canadian Association of Home and Property Inspectors (CAHPI). It was conducted at a number of venues from the period of 2005-2010. At the request of a number of interested parties, Cam is resurrecting the course, which will be updated to become applicable in today's building and inspection environment.

To date, we wish to express our appreciation for the endorsement by the Frontenac Heritage Foundation for this seminar. Both CAHPI and NHICC (National Home Inspection Certification Council) have recognized this course for education credits for home inspectors. We are anticipating further such credits from other home inspection associations and the real estate boards, as applicable, for annual education credits. 


Cam Allen L.I.W. NHI ACI will be teaching the history of heritage homes, heritage construction, types of wood assembly and all aspects of log, timber frame, post and beam, balloon frame and platform frame and roof assembly. He will be teaching foundation assessment and related methods of preservation and repair.

Paul Zammit, Cam's partner, will be assisting during the presentation. Paul has over 20 years of heritage home experience and his last major project before joining All-Tech nearly 2 years ago was the renovation/restoration of the 10,000 sq ft Heritage designated former Perth Courier building on the main street of Perth. Paul will be discussing heritage plumbing as part of this 2-day seminar.

We are in discussion with a heritage mason to attend and teach a section on heritage homes, brick and stone assembly, deficiencies and methods of restoration and renovation in regard to preservation.  A master electrician with extensive heritage experience will discuss and explain the issue of knob and tube wiring, ungrounded circuitry and wiring issues that relate to a heritage home. A certified air quality specialist will teach a section on asbestos, lead, mold and related indoor air quality issues, methods of remediation and the costs involved. The instructors names and background will be provided, likely in September and applications will be in late July.


While there are some brief courses available, there are no degrees in heritage homes inspections, making actual hands-on experience invaluable. Inspection of older wiring, heating and plumbing, for example, can only be understood when the inspector has a solid background in heritage buildings.  Understanding the different methods of assembly is also critical in conducting an inspection on a heritage building.

Past renovations and upgrades can sometimes present a particular challenge, as they have often not been done professionally.  While many issues are obvious, and have been reflected in the price of the home, understanding the dimensions of the issue is important.

Repair costs of a heritage home usually exceed those of a conventional or more modern home.  As an experienced heritage inspector who "packs" a wealth of knowledge, we can prioritize the issues and explain them to you.

A heritage home inspection often takes longer to complete.  You should plan on attending and allow up to four hours of your time. Bring along your notebook and a camera.

Time is taken with the client so that he/she understands the dynamics of the building, the options available and the best method to arrive at the necessary repairs and maintenance that are always found in a heritage home. Special attention to the wiring, heating and plumbing is necessary for you to meet the ever-changing insurance requirements.  Understanding insulation, ventilation and roof coverings of yesteryear, takes a particular expertise.  Heritage buildings are truly individual when it comes to the life span of a roof covering.  Metal roof coverings can be deceiving, the "tin shingles" can have widely varied life expectancies and a knowledgeable heritage inspector will evaluate the condition and maintenance required.

The skills of our forefathers were as varied as the designs of the homes.  As a professional heritage renovator, we bring personal insight into the individuality that every heritage home presents.

What to look for:


Peeling paint, foundation cracks and any other damage that should be dealt with now to avoid more serious problems in the future.


Typical in old homes, this can cover everything from cracked plaster to small movements in the foundation.  While they are not likely to cause the house to fall down, they should be corrected before they become more serious.


Probably the most common problem found.  Installation of new roof gutters and downspouts, digging up the weeping tiles or simply re-grading the surrounding lawn to re-direct the surface water away from the house, can reduce water invasion.


Common in older homes - undersized services, aluminum wired and knob-and-tub wiring or inadequate/poorly renovated distribution systems.  These may be unsafe and could be an insurance issue.


It is also quite common to find creative plumbing in older homes.  Galvanized and cast lines can become an insurance issue.  Repairs can range from simple to very expensive.


Metal shingles are common and have a very long life span compared to asphalt shingles.  On average, an asphalt-shingled roof lasts 15 to 20 years, but if there are multiple layers, the life span will be reduced.


Most older heating/cooling systems are inefficient.  While replacement may seem expensive, the new, more efficient systems will reduce heating and cooling costs substantially. With the price of fuel today, the capital outlay would be recouped in a very short time.


Excessive moisture from unvented bathrooms and cooking areas can damage plaster, deteriorate windows and cause allergic reactions.  These conditions need to be corrected before the deterioration becomes excessive.

On a more personal note!

For years, Cam has been addressing issues pertaining to heritage homes in his columns for Sun Media, which appear weekly in the Kingston Whig Standard.  The GreenTech-the series column addresses new and advancing technology for today's environmental responsible, energy efficient homes. On a personal note, Cam converted a rural United Church into an energy efficient, sustainable residence. Part of the renovation was assembled to International Passive House Standards.  To read the columns detailing restoration, renovation and new build, go to:

One of the reasons we took Paul on was to do with his extensive Heritage experience. His last project being the restoration and renovation of the Perth Courier Heritage Building in Downtown Perth.

We appreciate the very thorough informative inspection you did on the property, and I would have no hesitation in recommending you."
