"Prompt, professional and courteous"
Attended a property August, 2015 in Macclesfield where the floors had
become soft under the carpet tiles.
Dry rot has been popular in older properties recently where they have been left empty.

What is this Blog about?
It is here to give some idea of my working life; problems I come across and some thoughts.
Survey of two Bungalows in Congleton, House in Madeley - most interesting, Grade II Listed 16th Century farm house in Lower Withington, HomeBuyer Survey of modern semi-detached house with impressive views in North Wales
January, 2017 I was asked to undertake another School
Careers presentation on my job and that of RICS.
Concerns raised this week have included movement to a rear wall on a two storey house. It was found to have very little lateral support.
Damage to Brickwork
Historic House Surveys
I have attended older houses in Little Budworth, Eaton, Delamere and Suddington.
Some houses may not be too old, but their development over the years needs investigating. Properties surveyed in Bollington and Biddulph can be quite different, but the investigation can reveal the same detail that has deteriorated and needs remedial work.
A Building Survey had me investigating in Scholar Green and Mow Cop.
A particular interesting one was a historic Regency building where there was dampness under the front elevation windows.
The sides of the window reveals had been cement rendered and the cills heavily painted.
The age and the reveals were the giveaway.
In this case the relocation of the windows exposed the back of the stone cills, though heavily painted, water seeped behind the cill into the property and under the window.
The below image was taken after the outer wall skin was removed. The circle shows the rotten cavity wall tie.
I recommend specialists where their services would advise upon areas of concern that I may have. This particular one had bulging external walls, but vertical internal walls. I therefore recommended a cavity wall tie specialist.
I noted recently horizontal cracks in the mortar of a house in Endon, Stoke-on-Trent where the metal wall ties were corroding and lifting the walls. BIG JOB.

The trusses inside the loft space have twisted through loading on the
roof caused by winds.
Further loading could push the wall out or collapse the roof cover.
The ideal solution would require a new roof.
A floor survey in Wilmslow involved cutting out sections of the wood
laminated covering and boarding by the instructing party. This was perfect
in revealing the size of timbers used. A quick calculation showed that
the timbers were of insufficient cross section to support the kitchen/diner
floor especially as the kitchen island extended into the centre of the
room with a granite worktop over a fridge and washing machine.
Woodworm - Wood Boring BeatlesI
I have been asked to investigate the source and advise on the measures necessary to eradicate woodworm.
The property was in Chapel-en-le-Frith a large farmhouse having had serious works to alter it to its current layout.
Beatles, the size of a pencil lead, were on carpets and window cills. Beetles fly between March and September.
The exposed roof beams, softwood timber including the very limited height loft were inspected.
There were new flight holes in a beam to the ceiling in the fifth bedroom, but not enough for the number of beetles found.
I then re-examined the furniture, turning cupboards and drawers over.
The item had to be removed to outside immediately.
All timber in the house had to be treated. The chemical applied will kill the larva and beetle when ingested.
A small conservatory in Tytherington was investigated with the report that there was structural movement that a mortgage valuer could not explain.
My investigation found that there was a horizontal crack at damp proof course level and a vertical crack at the wall joint with the house.
There is quite often rotational settlement caused by poor foundations to the conservatory, but not horizontal.
It was found that the structure was built over the rear foul drains and that the side nearest the boundary was 18 inches from a deep man hole with cast concrete rings.
Conclusion: Typical poor shallow foundations to the conservatory caused the rotational movement; the brickwork nearest the house sits on the house foundations.
The horizontal crack is over the trench and deep man hole excavation without any bridging.
The light upper conservatory frame and brickwork above the dpc is not dropping/settling further as it is sitting on the wall ties to the back of the house abutment.
The boarding to the underside of roof overhangs is called a soffit. Recently I was in Bowden, South Manchester surveying a very impressive modern house and found dampness to the soffit boards near the gables. The roof covering was intact and good as was the gutter.
Closer inspection, in the rain, revealed dampness on the backside of the barge boards to the lower gable edge.
The problem was damp was running off the roof covering and over the edge cement and cloak, down the inside of the barge board onto the soffit and just sat there.
The cause was the lack of a roof verge edge lift. Raiwater when it runs down a level slope fans out into a delta, it never runs straight down due to winds and textured finishes.
The edge tiles required lifting to shed the water back onto the greater roof covering. A shim or cant edge of 12mm would be sufficient.
The effect of stone and brick surfaces flaking off the structure.
When stone is first extracted from a quarry it is soft and the "quarry sap" moisture of the stone dries out causing case hardening of the stone. Whilst soft the stone can be tooled. The detail on this stone is called broached.
Spalling can occur naturally by weathering, by poor maintenance i.e broken downspouts, by salts coming to the surface and not so common now, but air pollution.
Un-supported chimney stack.
Chimney stack in bedroom with horizontal crack!
The house is a mid terrace in Congleton, Cheshire built circa 1850. The rear bedroom has been replastered with new shallow skirtings fitted.
A simple one this. The Chimney breast in the room below had been removed. Thus no support.
Congleton Roof Problem
Wilmslow floor survey
"new offices at"
Why does the slate or come to that most roof coverings fail?
The slate covering fails:
When repairing the roof use the same type of slate. Slate comes in sizes that are given names such as 'duchess' (24"x12") and 'small lady' (14"x8").
The adage goes that 'you get what you pay for'.
Use copper nails instead of the zinc coated galvanised nail.
Replacing slate with concrete tiles should be avoided as they are twice
Spray foam to the underside of the roof. It will hold water if the roof
leaks and cause problems such as rot to the structure.
Un-compacted sub-floor fills.
This is noticed where the concrete floor has settled.
The normal procedure during construction is to compact with a flat mechanicl vibrating plate to every 100mm depth of fill.
We have inspected several houses recently where the internal floors are noticably concave.
On one inspection the builders were called in and undertook a core sample. Once through the 150mm floor slab they had hoped to find the fill. However none was found until they had put their hand into the hole to an arm's length (600mm)!
The concrete floor was being held above the fill by the slabs friction to the side walls. If six or more people jumped on the floor together it would drop the 600mm. Scary!
