Cannon Contractors timber and damp survey is easy because our staff have processes in place from the first enquiry. Upon taking your call we take down as many of your details as possible for the damp and timber survey. Now you may wonder why Cannon need to take so much information from me at this first initial contact. Our industry experience make us understand that taking all the information we need before the survey begins works best. Once surveying starts there can be so much information to digest that asking for contact details gets in the way.
On booking a survey our customers are advised by our office staff that we do a.m (10-1) or p.m (1-4) slots and cannot give exact times. However, upon your appointment been placed automatically into the surveyors diary you will find that our surveyors are highly organised and upon making the appointment where possible customers do receive a call from the surveyor just to confirm the arrangement again with an approximate time guide for their survey.
Naturally at the time of the survey the surveyor will examine the areas in which needs his attention and using his knowledge and experience will start to gather a diagnosis. A Protimeter MMS will be used to measure the area in question. The Moisture Measurement System is a powerful and versatile instrument for measuring and diagnosing dampness in buildings and building materials. This product enables the surveyor to measure moisture levels of building elements such as walls, floors and building environments simply by switching between the three different modes of operation. In this way, a detailed understanding of the moisture condition of the property can be obtained.
Now the Hygrostick and Humistick probes measure relative humidity (%RH) and ambient air temperature (TAIR) in rooms or materials. They can be connected to the Protimeter MMS instrument either directly or by means of the Hygrostick/Humistick extension lead.
• The surface temperature sensor (TS) is used when investigating condensation situations.
• The moisture probe gives percentage moisture content values in wood or wood moisture equivalent values in other non-conductive materials.
• Deep wall probes are used to obtain WME values deep below the surface in solid structures such as walls and floors.
Once the surveyors has assessed and tested the area he will briefly discuss with you the outcome and advise you on the treatments available, leaving you to think about your options. We will send a report to you with a detailed outcome to the survey. The surveyors’ recommendations, generally within the first twenty four hours of the visit.
We do keep lines of communication open from the very start of the survey taking place for your convenience. The surveyor provides contact details and is on hand to answer any questions or run through the report. A member of staff will contact you after a few days to make sure that you fully understand the report. We provide great customer service and always collect feedback to ensure our customers are happy with the service provided.
Understanding the type of damp that is affecting your property is important in order to cure the issue. This way you will not waste money on unnecessary work. Therefore it is vitally important toknow the type of damp as treatments for the damp all vary. There are three common types of damp that can potentially affect your property.
The type of damp as stated previously has a totally different treatment, though can be misdiagnosed – leading to incorrect treatment. So hopefully this post will steer you in the right direction. Condensation is probably the most common form of dampness affecting properties in the UK.
This is where warm moist air condenses on a cold surface, typically external walls, as they are colder than the internal walls. The condensation period is from September to March and therefore condensation is generally a winter issue. Poor ventilation increases condensation issues as poor ventilation allows moist air to remain in the property that can then condense on cold surfaces. Condensation has increased over the years since the introduction of double-glazing, central heating and loft and wall insulation. Modern property have more ventilation and is therefore an inherent problem for older property. The older property cannot ‘breathe’.
Rising damp is caused by ground water moving up through a wall or floor – referred to as capillary action. In newer properties a barrier is installed at the time of construction. This damp proof barrier, or damp proof course as it is commonly called, is run horizontally around the property at 150mm (6 inches) above the ground. The damp proof course is installed to stop rising damp.
Depending on the age of the property damp proof courses were not installed in houses built prior to 1870’s, and as the property ages the original damp proof courses begin to fail. Rising damp is a destructive form of dampness and can lead on to other issues such as dry rot.
Penetrating damp is caused by water penetrating through walls and may spread over ceilings and is usually caused by structural problems in a building. Things such as faulty guttering or roofing, or cracks in the walls, which mean walls or roofs are regularly soaked with water are likely to cause this type of damp. It can also be caused by internal leaks, such as pipes under the sink or bath.
It shows in often-isolated areas and can any where on the wall. If it is a gutter issue then the damp is noticed at the first floor ceiling area and starts to spread down the wall. Penetrating damp is more common in buildings that have no cavities. These types of property allow the dampness to quickly effect the internal fabric of the building.
So you have a brief introduction into the different forms of dampness and what to look out for. In all cases it is recommended that you obtain professional advice on to correctly diagnose the problem. A reputable damp proofing company recommend treatments and give you an accurate upfront quotation before the work starts.
