The non-invasive Building Survey will follow a disciplined iterative methodology and structural appraisal, including advice on loading and foundations to determine the structural serviceability and adequacy of property.  Survey will advise of all possible and probable defects and their causes some of which are contained in the menu below:

Stromness 13 Feb 2016 – The question of the smokey fire

Safety First – fire = heat, fuel (carbon) and oxygen (o2).  When these 3 are correctly balanced the fuel turns to carbon dioxide (co2) and water (H2O) when burnt.  When they have inadequate oxygen the fuel turns to Carbon Monoxide an odourless, deadly gas which will put you to sleep before killing you. 

Therefore all open fires must be correctly installed by a Registered Engineer and must meet the requirements of Building Regulations.  The engineer will ensure that there is sufficient oxygen available via vents.

 A Smokey fire is a warning that something is wrong, it must be put out immediately and not used until corrected by a Registered Engineer.

 TheScience of a Smokey Fire:

 A Volume of gas increases as pressure reduces and reduces as pressure increases therefore it will expand to fill the available space or can be directed by physical forces where ever you want it to go

 When a fuel (say coal) is burnt it alters its state from a solid to a gas. The emitted gasses and particles (fumes) will fill a room if no other physical forces are in place.  The physical forces which generally act on these gasses are as follows:

Heat which will force the gasses upwards

A flue within a chimney which will force warm gasses upwards

Therefore if the fire is placed directly beneath the flue within the chimney the fumes will move upwards within the flue unless stopped by other forces such as:

 If the flue is cold a plug of cold air can restrict or prevent the fumes

Down draft from winds above can blow the fumes backwards

The fire opening must be less than 8 times the flue cross sectional area or the up draft will be inadequate and fumes will spill into the room

If the combustion is inadequate insufficient heat will be generated to assist the updraft and smoke and deadly carbon mon-oxide will enter the room

Bruce was exceptionally quick to respond to survey request and the survey was conducted speedily and extremely... thoroughly. Bruce organised access to the property via the estate agents (so I didn't have to send lots of chaser emails to either party). Definitely more

In August 2019 Bruce Spenser carried out a survey for me on a Victorian flat conversion, to a very high standard,... saving me from a potential bad purchase. He is highly professional and his vast experience is clear. Highly recommended. Subsequently I used Bruce to survey an alternative property in Dec 2019. Again his expertise did not disappoint and this time will result in a successful purchase subject to negotiations etc. Highly more

Bruce was recommended to me via my brother after he provided excellent party wall service when he had a dispute with... his neighbour and the council. Very happy with the service he provided. He is a fair and just person operating in what can be a very confusing and ultimately exploitative part of the more

I’ve met a few true craftsmen in my time, and I can say with confidence that Bruce is one of them. In less than week... of calling him to see if he was available, he had performed a comprehensive survey of a property with a tight time constraint I had put an offer on, sent me a full report, then called me to discuss his findings. Thorough, professional, timely. I can’t recommend him enough. I will be using his services again in the more

Bruce's home survey was excellent, thorough and prompt. Albeit he is roughly 50% more expensive than other surveyors,... his review has been tremendously valuable to us and helped us to potentially save tens of thousands of pounds of works that we would incurred into after home purchase. He discussed his survey in details, provided advice on the overall negotiation process and offered to further review additional documents to ensure our purchase is sound. We feel Bruce has been our partner in this process as opposed to a transactional advisor, simply completing his more
