CWE Renovations is ready to turn your project into a reality - no dream is out of reach! Our team of expert remodelers will give a thorough assessment & estimate for your project. Call today to get on our schedule!

"Our experience with CWE Renovations has been marked by a troubling lack of professionalism, accountability, and customer service. Despite having a comprehensive record of issues spanning nine pages, we will have to summarize the key points here to provide a clear picture of why we strongly advise against using this contractor. Project Timeline and Delays: We were initially given an estimated completion timeline of approximately 12 weeks for our basement renovation. Contrary to this, the project has now extended well beyond 18 weeks. We were assured on two separate occasions (6/27 and 7/11) that only two weeks of work remained. Unfortunately, scheduling has been disorganized, with no clear plan to ensure tasks are completed consecutively. For instance, the electrician's work remains pending with no definitive schedule, and the carpet installation, scheduled for August 19th, was delayed due to the contractor's failure to arrange for measurement until July 26th (despite us inquiring about this since 6/27). Communication and Accountability Issues: Our attempts to gather accurate information and resolve issues have gone ignored. We discovered discrepancies when we contacted Waste Management regarding the pickup of our bagsters, only to find no record of an order. Additionally, a metal rack has been left for 2.5 weeks in our driveway due to the contractor's failure to follow up with Home Depot immediately upon it being left behind by mistake. More concerning, we found that the electrician listed on our permit had no involvement with our project. Upon investigation, we learned that the permit was improperly filed under a business' name, and the electrician ,who worked for the business, was only working on our project as a side job, potentially jeopardizing their professional standing. Overall Experience: The most disappointing aspect has been the lack of communication and ownership. We are left with an incomplete basement and are now seeking a refund for the portions of the project that have not been completed as promised. Given these significant issues, we strongly recommend avoiding CWE Renovations for any renovation projects. Our experience underscores serious concerns regarding their reliability and commitment to customer satisfaction. Everything incomplete as 8/12 (18 weeks after the start date with a 12 week estimate): Electrician to finish outlets, lights, light switches, etc (no eta) â we paid for on 7/30 Carpet Installed (given a date of 8/19 which is completely unacceptable when we have been asking about this since 6/27) we paid for on 7/30 requesting this refunded since Carpet Installation Guy does not want to work with Dan and quoted us almost half to install Trim completed around stairs and in bathroom - Paid Metal Rack Removed from Doors (Offered to reach out myself since Dan doesn't seem to have any urgency in it) -Requesting Dan cover the cost to remove on 8/15 Garbage Removed (two bagsters) We paid for on 2/26 Door Installed over the breaker box Lien Waivers from Plumber, HVAC, Electrician Railing on the stairs (which we have made clear we do not want this in until carpet is installed so we can get our couch downstairs) Paid on 4/12 invoice"

Oregel brick paving is a locally owned company with 20+ years experience. Quality and customer satisfaction is always at the top of our list so we always bring our highest quality of work and customer service to every job that we complete. Our focus is to complete the job in a quick and timely manner with the utmost professionalism and work with our clients to create the vision they have to enhance their outdoor living space at a competitive price.

"Wonderfully!! They were and always have been excellent. We have a 50 foot patio with 3 sizes of pavers in a random pattern. A large section was removed, leveled and put back together exactly correctly. The entire patio was power washed, resanded and sealed. This was a 2 day job and the price was very good. We originally had 3 other estimates and were told that the old patio needed to be scrapped and replaced with a new patio for $25,000 to $30,000. We wanted to keep the same pavers (some of which were no longer made) and pattern, and Oregel were the only company that could do this and for a fraction of the other estimates."

At Alpha Ventures, we specialize in transforming your house to the home of your dreams.

Our goal is pass our reputation to our children and to build a company that will be here for generations. Authentic. Local. Passionate. Honest. Affinity for People.

"All of these 5 star reviews got dumped on the Angi page, dated 2/2024. All show shiny basements & what appears to be excellent work & reviews claiming excellent communication. It's how I came about the referral - as well as their Facebook ads. Not sure if they bit off more than they could chew, but communication has been awful if not non-existent. The home visit seemed great! But I had to email them for the quote afterwords. Then a visit to the showroom a month later was dirty, plant dirt lying around, no bathroom available to the customers, giant weeds outside of the building they purchased. If you're presenting yourself as professional contractors, appearance of a showroom where you host customers is a reflection of your work. I didn't hear from them in over 4 wks. I emailed & was met with an excuse & zero delivery of promise for final proposal. We are taking our business elsewhere. We just wasted 3 months for nothing."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
