Frequently Asked Questions (FAQs)
Q: How long does a mould inspection take?
A typical inspection takes 30–60 minutes depending on property size. We provide a report and recommended treatment plan the same day.
Q: Is mould removal safe for children and pets?
Yes. We use environmentally safe, non-toxic products. You can return to the treated area shortly after completion.
Q: Do you offer guarantees?
Yes. Most treatments come with a 5 to 10-year guarantee, depending on the extent and type of work carried out.
Q: How soon can you attend?
In most cases, we can schedule a visit within 2–3 working days — sooner if it’s urgent.
Q: Can you fix the damp issue causing the mould?
Absolutely. Renovani is a full-service damp, mould, and timber specialist. We don’t just treat the mould — we solve what’s feeding it.
Q: How do I know if it’s rising damp or penetrating damp?
Rising damp typically affects lower walls and shows salt marks, while penetrating damp can appear anywhere, especially after rain. During our survey, we’ll diagnose it properly and explain your options.
Q: Can damp proofing really stop the problem for good?
Yes — if done correctly. We focus on finding and treating the root cause, not just painting over it. Our work is guaranteed.
Q: Will I need to leave the house during the work?
Usually not. We plan around your schedule and work in sections to minimise disruption.
Q: Is your survey free?
Yes — our initial site survey is free, and we’ll provide a no-obligation quote with clear next steps.
Q: How long does the work take?
That depends on the extent of the damp and size of your property. Most treatments take 1–3 days.
Q: How do I know if timber is actually rotten?
Signs like softness, crumbling edges, or a musty smell are key indicators. During our survey, we use moisture meters and probes to test integrity below the surface.
Q: Can you repair timber, or does it always need replacing?
It depends on the severity. In many cases, we can treat and strengthen partially decayed areas. For advanced rot, full replacement ensures lasting stability.
Q: What if the rot is caused by damp or condensation?
We treat the root problem, not just the timber. Renovani also specialises in damp proofing, so we’ll solve moisture issues as part of the job.
Q: How long does timber repair take?
Most jobs are completed in 1–3 days depending on the location and scale of the damage.
Q: Is your work guaranteed?
Yes. All structural timber repairs and replacements come with a guarantee of up to 10 years, depending on the treatment used.
