  • Woodworm treatment, upgraded ventilation for whole house & invasive floor survey

    9Verified Review

    I had the following remedial work done after a pre-purchase survey: Timber treatment for woodworm PIV unit installed 1 extractor fan upgraded 1 extractor fan added Replacement & addition of airbricks to all sides of the property Further to a discussion about the subfloor, I also had an invasive floor survey undertaken. Clint took time to explain matters which helped me make appropriate decisions about what I ended up having done. The various employees & subcontractors that did the work were punctual, reliable and friendly. They did a great job and the work was completed to a high standard.

    This is the 2nd time I’ve used Biocraft Southwest to complete works. Great company to deal with good communication. Very knowledgeable surveyor with a superb team of professionals completing the work needed to sort out a damp wall and the reasons why it was damp. Very punctual, everything left clean and tidy after the jobs were finished and efficient. 11/10 I wouldn’t hesitate to use Biocraft South West again if I needed to. Thanks everyone

    We were very impressed by the speed and quality of the work carried out by Scott and Toby. They left the room clean and tidy at the end of each day. There were no hidden costs and every aspect of the work was made clear by Clint, who was really good at communicating with us at regular intervals throughout the work.
