5.0 Amit P. Waltham, MA

Ken was amazing!!! His customer service is outstanding. I hired Ken as I was in the process of selling my house and the buyer needed a Lead Certification. I called Ken to see if he can come out and do the deleading job as the closing was less than 3 weeks away. He was able to quickly get the job done in time (only 1 day whereas other contractors said 2 days). He was extremely reasonably price (one the very low end of the quotes I got). There was one quote that was lower, but given his customer service he had provided I went with Ken and it was a great decision. He was able to schedule a lead inspector for the same day and we passed the inspection. I actually needed his assistance with another job small job in order for me to sell the house (not lead related). He was able to go back to my home the very next day and get what I needed!! Again, his price was extremely reasonable. He could have charged me a lot given my time crunch but he did not which I am very appreciative of. I would not at all hesitate to hire him again if the situation arose. HIGHLY RECOMMEND USING KEN!!

Ken and his team were prompt, thorough, and professional. Despite unexpected obstacles (from my side, and no fault of KSC), the job was completed on time. I would use KSC again without hesitation.

5.0 Debra D. Mattapan, MA

KSC delivered on time restraints for this job and was informative on each step. From the beginning they were informative and help with steps involved. I would recommend them.

4.5 Kass S. Wakefield, MA

We used Ken and his guys for lead abatement. Very professional and answered their phones/ emails in a timely manner.

5.0 Brady L. Sherborn, MA

We hired Ken and the team to do lead abatement work which meant he had to replace a significant number of windows (15) in our very old house built in 1700s. These were not simple jobs! His attention to detail and his creativity in solving unexpected issues was valued greatly. He was responsive and professional throughout the process and worked wonders getting the work done in a tight timeline so we could move into our new home. You can trust Ken and his team to give good advice and do the job right.

5.0 Max S. Norwood, MA

KSC was very quick to respond, and highly communicative the whole project, which I always appreciate. They were able to do the work quickly, and professionally, with an excellent result. I will certainly be using them in the future for more projects.

5.0 Jing R. Cambridge, MA

Ken was responsive, professional and very helpful. He and his team came on time as scheduled. They worked very efficiently and cleaned up the work site very well. I recommend Ken and his team.
