Independent, evidence-based damp, mould and condensation specialists trusted across homes, rentals, care environments, commercial environments and social housing.

At JAG, our mission is simple: to help people live and work in healthier properties safely, confidently and without unnecessary disruption. We provide clear, independent damp and mould surveys, practical advice, and safe treatment solutions that people can genuinely trust.

For homeowners, landlords, housing associations, care homes and commercial property managers, we bring something refreshing to an industry that’s often confusing, inconsistent, or overly sales-driven.

Honest expertise, clear communication and zero upselling.

We exist to give people clarity when they’re worried, reassurance when they’re uncertain, and practical steps they can act on straight away.

Independent by Design

Most companies offering “damp surveys” are really providing quotes that steer customers toward expensive treatments. JAG was built differently. Our surveys are completely independent, meaning every recommendation is based on evidence, not sales targets.

You’re free to use any contractor you choose, and you’ll still have a clear schedule of works to follow. This transparency is one of the biggest reasons customers trust us.

Advanced Diagnostics, Clear Findings

Whether you’re dealing with condensation, black mould, a damp patch, leaks, or a long-term mystery issue, our surveyors use the right tools to get it right the first time:

Thermal Imaging

Moisture Mapping

Ventilation Assessment

Building fabric evaluation

Relative Humidity and Dew Point Readings

Every survey ends with a clear, plain-English report within 72 hours — including photos, findings, and actionable recommendations.

We explain what’s happening, why it’s happening, and how to fix it in a way that feels achievable, not overwhelming.

Safe, Non-Toxic Mould Treatment

When mould needs to be removed, we use COSHH-free, non-toxic treatment products — safe for children, pets, elderly residents and people with asthma. The treatment is strong but without the harsh chemicals many competitors use that can damage surfaces or irritate airways.

Where needed, we can apply Hale Defence + medical-grade coatings with antimicrobial, antiviral and antibacterial properties, offering added surface protection as part of a wider remedial approach.

Our aim is always the same: treat mould safely, effectively, and ethically — without cosmetic quick-fixes.

Repairing The Root Cause

Mould is the outcome, not the cause. That’s why JAG also provides Damp and Mould Services, fixing the underlying issues behind damp and mould. These works follow the report exactly with no guesswork, or unnecessary extras.

Repairs can include:

Surveys
Leak repairs
Non toxic
Ventilation improvements
ethical and safe
Gutter & downpipe corrections
social housing
Re-plastering and reinstatement
Specialist
General building and refurbishment works

This evidence-based approach dramatically reduces miscommunication and repeat visits.
