The problems homeowners face — and how we investigate them
Cold rooms, draughts, condensation, black mould, damp walls, high humidity, overheating — every one has a root cause you can measure. Find your problem below, then let a Building Performance Investigation give you a prioritised plan to fix it.
Cold, Draughts & Heat Loss
A cold home, cold rooms, draughts or high heating bills — find where your home loses heat and how to fix it.
Cold Home & Heat Loss Investigation
If your house is cold, expensive to heat, or has rooms that never warm up, more insulation is not always the answer.
InvestigateDraughts & Air Leakage Investigation
If your home feels cold even when the heating is on, the problem may not simply be poor insulation — it may be uncontrolled air leakage.
InvestigateCold Walls Investigation
If your internal walls feel cold to the touch — or you have damp, mould or condensation forming on them — the cause is rarely just 'the weather'.
InvestigateCold Floors Investigation
Cold feet and chilly floors are one of the most common complaints we hear — and one of the most fixable.
InvestigateCold Rooms Investigation
One room that never warms up — a freezing bedroom, a cold room above the garage, or cold rooms upstairs — points to a specific, findable cause.
InvestigateWall Heat Loss Investigation
Walls are one of the largest surfaces of your home — and often one of the biggest sources of heat loss.
InvestigateLoft Heat Loss & Insulation Investigation
Heat rises, so the loft and roof are where a warm home loses the most.
InvestigateFloor Heat Loss & Insulation Investigation
The floor is an easy element to overlook — but an uninsulated, leaky floor loses heat downwards and lets cold air up.
InvestigateCeiling Heat Loss Investigation
Ceilings below flat roofs, dormers and room-in-roof conversions can lose heat fast — and downlights and hatches let warm air straight out.
InvestigateThermal Bridge Investigation
Thermal bridges are the hidden cold spots where heat escapes and condensation forms — behind corners, around windows, at floor and roof junctions.
InvestigateHigh Heating Bills & Home Energy Investigation
If your heating bills feel far too high for the comfort you get, your home is wasting energy somewhere.
InvestigateUneven Room Temperatures Investigation
When some rooms are warm and others never heat up, the problem is findable — and it is usually a mix of where the home loses heat and how the heating is balanced.
InvestigateCold Bathroom Investigation
A cold bathroom is uncomfortable and, because bathrooms generate so much moisture, prone to condensation and mould.
InvestigateCondensation, Damp & Mould
Wet windows, black mould, damp walls or a musty smell — diagnose the true moisture mechanism, not the stain.
Condensation, Mould & Moisture Investigation
Black mould around windows, condensation on the walls, a musty smell that never quite clears — these are symptoms, not the cause.
InvestigateCondensation on Windows Investigation
Wiping wet windows every morning is more than a nuisance — it is a sign your home holds too much moisture and its surfaces are too cold.
InvestigateBlack Mould Investigation
Black mould is a symptom, not the problem.
InvestigateDamp Walls Investigation
Damp walls are treated wrongly more often than almost any other home problem.
InvestigateHigh Indoor Humidity Investigation
Persistently high humidity makes a home feel clammy, smell musty and grow mould.
InvestigateLoft & Roof Condensation Investigation
Water droplets on the underside of the roof, damp insulation, black mould on the rafters — loft condensation is common, and left unchecked it rots timber and ruins insulation.
InvestigateVentilation, Air Quality & Comfort
Stuffy air, poor ventilation or a home that overheats in summer — get a healthy, comfortable indoor climate.
Indoor Air Quality Investigation
Stuffy, stale air, lingering smells and condensation are signs your home isn't breathing properly.
InvestigateHome Ventilation Assessment
Ventilation is the most misunderstood part of a healthy home — too little causes condensation and mould, too much wastes heat.
InvestigateOverheating & Summer Comfort Investigation
A home that's too hot in summer is as much a building-performance problem as one that's too cold in winter.
InvestigateOne investigation finds every root cause
Most homes have more than one problem, and they interact. A Building Performance Investigation diagnoses the whole building at once and gives you a single prioritised plan.
