Ryedale Testing take the hassle out of testing calculations by providing a local, quick, accurate, and integrated service… all under one roof! Ryedale Testing is an ATTMA member and use only the highest quality UKAS calibrated instruments.

From April 2006 Part L of the Building Regulations were amended to reflect the Government's continued commitment to the reduction of green house gases and wasted energy. All new domestic dwellings with just a few exceptions are required to demonstrate an air tightness of not less than 10m³/(h.m²)@ 50 Pascals.

ACCURATE RESULTS

• We commit to spend more time sealing up your property in accordance with ATTMA guidelines, which means the prescribed level of air tightness is achieved.
• Results are only as good as the quality of the build and the accuracy of the test.

• If required, just call our emergency number 07946 315 721

Achieving air tightness

Check list - prior to the test:

• Access for fan equipment to be installed
• No airflow restrictions in front or around fans – a clear door opening is preferred
• Electrical power (240 Volts)
• Windspeed less than 13 mph
• All mechanical ventilation/heating systems to be de-activated
• Consider local restrictions eg noise, working hours
• Acceptable route for the air to flow from the fans
• Workforce can remain in the building during the test but access in/out of the property is forbidden
• Depending on the volume of sealing required a typical test should take 1-2 hrs

Costs

To ensure we offer the most competitive price we estimate each project separately, there are attractive discounts available for multiple tests.

We provide two levels of service, a routine test with a 14 day lead-time and an emergency test for projects where time lines have slipped.
