Retrofit Hub

PAS requires a Retrofit assessment before any Retrofit work is carried out. The assessment includes:

Condition Survey: This is a very important part of the process. The report highlights current issues with a property, evidence of issues, and maintenance that should be carried out prior to any Retrofit work.  This report provides information from water ingress/leaks, blocked or leaking gutters & downpipes, moisture issues on walls, slipped roof tiles, damp readings on walls to general condition of the property. Addressing issues such as these is extremely important as covering them up may cause a breakdown in the integrity of the building and a failed Retrofit, which would accelerate the issues.

Occupancy Assessment: This is used to highlight behaviour and usage in a property such as water usage, how the property is heated, fuel type and how the current heating systems are used.

Ventilation Survey: PAS adopts a ventilation strategy which, in effect, brings the retrofit property up to current building regulations in terms of ventilation requirements. It takes into account under-door gaps, correct extraction in all wet rooms, and background ventilation. Insulating a property seals the air tightness of a dwelling, which reduces air movement and can lead to very high humidity and poor air quality. This is not good for the building or its occupants and in turn can cause interstitial condensation. PAS follows the mantra “insulate tight, ventilate right!”

Significant Survey: If a property is located in a conservation area, an Area of Outstanding Natural Beauty, or is listed, PAS requires that a significant survey is done.  This takes into account extra details such as decorative brick patterns, important townscape, natural materials and historic features such as original windows, beam, floorboards, etc. This ensures that extra care is taken to protect buildings with historical importance that may be lost in retrofit projects. These considerations may influence the measures that we recommended.
