**★★★★★ — M Biallas, Nov. 2014**

> From our first contact with Paul and Cornerstone Renovations LLC, it just clicked!
>
> Our project was the installation of a custom family room entertainment center. The prep-work involved a re-work of the electrical outlets and additionally new overhead recessed lighting, along with closing up the drywall and plastering, following the electrical work.
>
> Paul's estimate of work was right-on, everything was clearly explained and there where NO surprises.
>
> Paul and company timed all the prep-work perfectly and stayed in-touch with the cabinet maker as to when the cabinets where to be delivered.
>
> At the end of each day of work, the family room was throughly cleaned and we where briefed on what to expect next.
>
> On the day the cabinets where delivered, Paul and crew where at the ready and choreographed the unloading of each cabinet and promptly began installation.
>
> The following day, the cabinet installation was finished and the family room throughly cleaned.
>
> I was totally impressed with Paul's attention to detail, the quality of his work and professionalism.
>
> My wife and I can't recall the last time we had such a great working relationship with a company that provided top-notch services.

> Hire Cornerstone Renovations if you want it done right.  These folks are the best! We hired them for our bathroom remodel and couldn't be happier.  From the first consultation, to the last finishing touches, they're are top notch professionals!  We were impressed with how responsive they were with any request or concern we had and they met our deadline by two days early!!  It made me feel a bit calmer during a home renovation which is sometimes hard to feel.   Our bathroom turned out gorgeous!!  I can't wait to use them again for more home renovations.   I feel lucky to have finally found a reliable, professional and talented remodeling company.

**★★★★★ — mjcrowley8, Nov. 2014**

> Cornerstone Renovations exceeded my expectations and did an absolute wonderful work in our home renovation.  Paul not only came in with ideas of how to approach some tricky elements, but also shared some of his vision around the study and mudroom.  Since it was a tight space, it was an iterative process of where walls might fit, creating enough space for appliances and doorway dimensions.  Paul directed us to a great custom cabinet supplier and he was an advocate for us in that relationship.  All of the subcontractors were professional and very accommodating.  Cornerstone and all of the subcontractors were VERY clean throughout the process Paul was always attentive, patient and responsive to our questions and followed up with any concern we had.   We are considering more work and Cornerstone will definitely be the involved.
