"Matt and his team with MNB Renovations did a 32 x 24 addition that was basically a home build from the ground up. I am still surprised for the size of this project how stress free the process was. Matt was very detailed and checked in on everything to make sure we were getting what we wanted. In the end he asked us to make a list of anything that needed to be addressed and there was absolutely nothing to mention. They did a perfect job, the quality of the work is amazing, and the entire team was very nice, professional, and trustworthy! I absolutely recommend this company to others and will definitely use them again in the future!"

"I am so happy with my new bathroom! The men doing the work were excellent! They were very professional, yet very friendly and listened to questions I had and answered them so I could understand them. I would definitely recommend Berks Commercial Renovations to my family and friends. Dean and Courtney were so wonderful to work with to help me with all I wanted for my bathroom. Great experience!"

"This was the third time I used Mark and he did a fantastic job. The bathroom was a challenge because the space was awkward but needed a shower added. Not only did he find a solution, but it looks great and really improved the value of the property. He did work throughout the house and even redid his work on the front porch railing after a brief conversation about making it look better -- the way he redid the work went above and beyond what I expected and really made everything look so much better. I keep going back to Mark for his work and highly recommend."

"I am pleased that my bath rooms are much nicer than before the project.  I was disappointed with the way it was completed.  I asked as the onset the approximate time frame and I was told two weeks.  There were a few change orders but by their own time estimates it would have been a 3 week project.  It took 6 weeks and it ended because I just could not take it anymore.  You start with Alex who I do believe would like things to go well but he subcontracts and then really loses control.  The contractor works usually 9-12 or 9-2p.  In the six weeks, there were only a couple of days that were complete 8 hour days.  Beware of the term contractor grade in the bid. I was told that this was a better grade of product but it was not.  I ended up purchasing the majority of the products used and was told that I used very high grade products.  My products were just purchased from Lowes and Home depot and were not the "top of the line".  Also, there was very little concern over respecting my house.  The project was extremely messy--not just construction dirt.  I fully expected plenty of dust and dirt but there splattered paint. It is obvious when I clean my "high grade" floor tile, which I do by hand, that a lot of paint was spilled and not completely cleaned up not totally noticeable until I cleaned it the first time.  In addition, the tub has two chips, again not noticeable until I cleaned up the mess left behind. My hardwood floors are scratched.  The excuse for this was being passed on to a sub-subcontractor plumber.  I don't know who did it I just know that it is done.  The offer to fix it was to "try" to cover it up.  I live in the country and trash removal was a mess.  They did not provide the dumpster that they said would happen.  The trash was piled up outside the doors and I am still picking up pieces of dry wall, pipe, broken fixes, etc.  Be sure to demand the dumpster.  I was told it could not be delivered to my house this is not true because I have had large dumpsters in the past.  I believe this was a cost cutting on the part of the contractor.
I grade them an overall C based on how bad my bath rooms were and the fact that they are now better. I am just warning you that you need to be aware of the process concerns that I have listed above.  The 6 weeks cost me additionally, paying a nephew to sit with the house the majority of the time since I have limited vacation time and not expecting 6 weeks. It is difficult to take vacation time from work and have them work just 4 hours.    I began thinking that this became a money pit.  The cost above is not inclusive of all the expenses of this project. 
I have waited to write this review to make sure that I am fair in my response.  I have given it time and all of the above is a fair "nutshell' evaluation of the project."

"Dan is a dream come true! Not only an expert craftsman, he's also incredibly talented and an absolute pleasure to work with. His work is always A++++ We have done extensive work to the exterior (front and side entry) as well as an oak timbered porch. He, along with his son Tyler framed and tiled a full mud room with gorgeous custom bar. He has also sanded floors, built custom shelving, replaced all stair railings, built a custom bar, the list goes on! His knowledge of material is unparalleled. Most importantly Dan is a wonderful person. He is extremely patient (as I change my mind from time to time!) He is always on time and so respectful to our property. He takes immense pride in his work, and no job goes unfinished. He pays attention to every little detail. In short, since we found Dan our home has turned from lovely to extraordinary. I can't say enough good things and would recommend him over and over again."

"Great experience from end to end. Lance took the time to explain options and product features as well as timing. He made the sales process comfortable and easy. Installation was completed by Tim and Don. Tim called to confirm in advance, showed up on time, and completed the entire installation in under 5 hours. Everything was clean and the new windows look great. Will definitely use again."

FAQs for addition to existing structure building service projects in Douglassville, PA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
