TWC Real Estate Ltd

My names Tom, I have been in the real estate sector for over 10 years and have done everything from general property maintenance, new bathrooms, painting/decorating, demolition contracts and most recently constructed 9 ultra high spec homes. High quality and impeccable workmanship are key values to me and ensuring the client is satisfied and more with the work they are receiving. I have decided to further expand and diversify my business reaches and so my rated people account is new, however my experience in the industry is far from that. I am very well connected with all trades and can provide a top tier service for all types of project management no matter how big or small the job may be. I am also extremely capable at doing many manual labour jobs, but often favour a shorter timeline for my clients project completion and therefore prefer to draft in experienced trades to get the job completed. Above all I am very friendly, well spoken and always keen to deliver what is asked of me.

This was one of those jobs that had various problems from the start. Having said that SMS did put them all right without complaint. The quote given for the clearing of the site AND the complete redesign was excellent. The original deadline was missed by a long way primarily due to misjudging the anomalies of the site (eg the underlying concrete was a lot thicker than anticipated). SMS were slow in clearing the site after the work was done - it took almost three weeks before the last of the rubble and debris were moved. Overall, I am pleased with the work done and the final result and would be prepared to use them again.

Consequently I only received a disc containing corrupted files, and when they re-took images of my drains i did not receive a file at all. And when I queried if a section of the relined drains was properly sealed they failed to return to my house. I recommend anyone not to part with any money until completely satisfied.
