    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.

    5.0 Jennifer P. Dedham, MA

    Ken paid attention to what I was asking for, and was responsive and thorough. Did a nice painting job, including cleanup and post-project touchups. Would recommend.


    Very knowledgeable and easy to work with.

    5.0 Ben D. Cambridge, MA

    I could write a really long review about what a wonderful job Ken did. But to be (somewhat) brief.. Before the job: he gave candid advice about what should be done (even though often reducing the size of the job), was in touch all the time, and made quite a few (free) visits to get everything measured and ready. During the job: We had to be out of town to get my son away from the job site and we picked a week to do the work months in advance and he amazingly stuck right to schedule. Even further, the job had some surprises and took longer (not his fault) and he burned the midnight oil to get the job done so we could come back to the house on schedule. After the job: he helped (and is still helping) follow-up with the manufacturer about an issue and is providing some other lead advice; he didn't at all just disappear when the job is done but provides the same level of contact he did before the job (which, frankly, was already way better than his peers). I hope this illustrates what was really a fantastic experience I had working with KSC. Ken is one of the (seemingly few) people who aims to build a business through reputation for integrity and not short-term money grabs.


    Strongly recommend Kenneth for deleading project.

    5.0 Ami S. Brookline, MA

    I highly recommend Kenneth Corb for anyone's lead removal project. I hired Ken to de-lead a single house in Brookline, and I couldn't have asked for the project to be managed by a more trustworthy professional. Ken is an expert in his field and is happy to share his wealth of knowledge and experience. He took the time to explain the process and discuss the various options, and then took great care of the property while getting the job done. Ken and his team worked extremely hard to complete the job in a short time. Ken coordinated the process with other professionals (like window ordering, delivery, and installation), checked in with the lead inspector to make sure that the solutions he is working on are what the inspector would expect, and communicated daily with me as he moved the project forward. In short, he made what could have been a complex project, very easy for me. He has an exceptional commitment to customer service and knows that many of us go into a de-leading project with much anxiety about the process. I am thrilled to have had the good fortune of working with a real professional. Would hire Ken again anytime.

    What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

    1. Verify Trade License
      HomeAdvisor checks to see if the business carries the appropriate state-level license.
    2. Verify Insurance
      As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
    3. Verification of State Business Filings
      For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
    4. Criminal Records Search
      HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
    5. Sex Offender Search
      We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
    6. Bankruptcy Search
      We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
    7. Legal Search for Civil Judgments
      We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
    8. Liens Search
