Alder - Specialist Building Surveyors

Alder - Specialist Building Surveyors Independent / 35 years exp / Qualified Surveyor Timber / Rot / Woodworm & Damp Defects. My name is Pat McLellan, a Canadian from Vancouver Island. Pat McLellan

My ethos "I independently survey, using specialist forensic equipment to honestly tell you what / if any treatment is required & I will save you money". I moved over to the UK in 1983. I am the sole proprietor of Alder Specialist Building Surveyors Ltd. or, A.S.B.S

About me:
I have been in the timber decay/woodworm/damp industry for over 35 years. I worked my way up to directorship of a nation co

mpany, then started my own successful company (Alder Timber Preservation Ltd.) and ran that for 21 years (without any claims on guarantees issued!). 7 years ago, I started ASBS, which was the consultancy & project management arm of preservation the business. I shut the preservation side down 6 years ago and to focus on the consultancy and “forensic style” external & internal building defects surveying and project management. With over 35 years of experience and numerous qualifications, and a healthy investment in hi-tech surveying equipment, I have learned how to make buildings give up there hidden secrets to me. My ethos in this profession is to provide an honest assessment of a property that may have building related defects (inclusive of rot/woodworm/damp) and endeavour to provide the reasons why, how bad they are and offer assistance on remedies (most of which you can sort out yourself), through my detailed reports provided. I can even provide budget costs & project management. One of the most outstanding aspects in my ethos is “if it doesn’t need works/treatments, then I will tell you that” and put it in writing. This is how my surveying approach differentiates me & this is how I can help you save money as I am not undertaking the survey looking to get the follow up work to fix the problem. If the issue is small or something you can fix yourself and more often than not, it is something you can treat yourself then I’ll tell you. Equally if it’s a huge job I’m not afraid to tell you the full extent because I don’t have a vested interest in securing that aspect of the work. The housing market in Scotland is lead by the Home Buyers Report, often referred to as HR. My professional colleagues providing the HR’s, provide a wealth of information on a property, though it is not in there remit to focus on the specific details of defects, and I know this frustrates them. That is why they categorise defects or “potential” defects from 1-3, and follow that by recommending you consult with a specialist in that field and in this market, that is a main feed for the preservation industry. To bore you further, between January 2015 to November 2017 I visited 644 domestic properties. (I also do a lot of commercial work). Out of those domestic properties inspected, 94 of them (14%) had no issues at all. 193 (30%) of them were misdiagnosed (example being woodworm being called “active”, when it was “inactive” , then treated unnecessarily)….that is a fact! Moving forward to 2022, I estimate that 7 out of 10 properties I have visited require minimal, if not “no works/treatments” with regards to woodworm/decay/damp and I report that accordingly. Often the money lending institutes will usually only lend the full sum required on the basis of defects highlighted in the HR being rectified and long-term guarantees provided. My findings of “no treatments required” have never been rejected and have always been accepted by the money lenders in my 35 years of operation. If you are looking for a reliable, friendly, honest and thorough assessment of one of the biggest investments you might make, it maybe worth your while to drop me a line and or have a look at my website www.aldersurvey.com.

“Woodworm” – The facts:
What comes first: The beetle or the egg? (One of Mother Nature’s greatest secrets!)

Questions often asked……:
Does the Common Furniture (the most common beetle found in properties around here, hence the name) – bore into the timbers?....... Answer...No!

I think I have an active woodworm infestation?... (Do some basic detective work yourself and do not always believe what you are told, as there are a lot of people looking to make money out of treating your timbers, regardless of if it is active or not!).

The photos below will hopefully give you a better understanding of the process:
Fibre-Optic Photo No 1- “The Eggs” Very seldom seen as they are minute and are laid inside the timbers. That is where the fibre optics come in handy.

Fibre-Optic Photo No 2 – “The Larva” (the actual “woodworm”). According to the Institute of Wood Science and the British Research Establishment, the common furniture beetle can live inside the timber and happily chew away and feed itself for up to 4 years undetected before they emerge as adult beetles.

Fibre-Optic Photo No 3 – “The Adult Beetle” At the end of Larva cycle, they carve out a pupation chamber just below the surface of the timber and do the metamorphosis thing and chew their way “out” leaving behind the “Bore Dust”. From there, it is estimated that they will live for 3-4 weeks in search of a partner, do their business and then the female lays her eggs in the cracks/crevasses of timbers or even old exit holes. And the whole process starts again.

Photo No 4 – “The Exit Hole & Bore Dust” To the untrained eye, the bore dust around and “exit hole” is the first indicator you look for. Other things you can look for are the dead carcasses of the adult beetles, often found on windowsills. They usually emerge between late March to the beginning of September, depending on the climate.

Treatments – its not rocket science stuff, especially with modern water-based formulations that are less toxic than most of the chemicals you have in the cupboard under your own kitchen sink. It’s a dirty job, but one you can do yourself if you are a “DIYer” as long as you do it properly and are not driven by the almighty long-term guarantees that money lenders insist upon.

Dry Rot Farming – The “Myth” Can wet rot turn to dry rot? In my experience and research, the answer is “No”, the reason is that they are to totally different animals, like a Cat vs Dog. However, wet rot can be overtaken and infected by dry rot if the dry rot spores are present and the moisture contents favourable. Research says moisture content of 0% -20% is safe…20%-30% dry rot can germinate…30%+ is to wet for dry rot to thrive. So, I did an experiment. (Some people have said I need to get out more! 🤣) Have a look at the following photos.

Photo 1 - Dry “wet rotted timbers” placed in a plastic container on a bed of dry bark. I added a little piece of fresh dry rot mycelium (circled), and then a bit of water to get it all up to between 20%-30% then covered it and stored it away.

Photo 2 - After 3 months, dry rot was beginning to form.

Photo 3 - After 6 months, it was thriving!

Photo 4 - Look how the dry rot mycelium even attaches to the plastic. Dry rot mycelium will travel through masonry, across steel etc., in search of food which is basically anything organic. Often, this happens behind walls and under floors unseen until the fruiting bodies appear, by then it has started to recolonise and you’re in trouble!

THERMAL IMAGING SERVICES

Check out the first photo of the toilet - can you spot any problems?

Look a bit closer, and look at the second photo. The dark blue colours indicate damp and whilst you'd expect the cistern to be damp (it's full of water and cold) it's the area in the corner that is the concern.

Our thermal imaging services pick up problems that the naked eye can't spot.
