Small business, self employed, use subcontractors that I can trust, minimum consultation and visit fee $295. That includes, site visit, inspection, and a verbal on site report and follow up with contractors as needed . The fee for site visit and inspection is a flat fee, basically it is the charge to drive to your location and provide a verbal report. This fee does not include a written formal report. A written report is approximately an additional $300. I work evenings and weekends as needed, structural, architectural and mechanical design, inspections and reports, fronsic, expert witness. Please contact by phone or email: [email protected]. I will be on Vacation from July 9th till July 25th

"Kamran was easy to coordinate with and schedule the inspection. He was prompt and thorough with his review. His write-up was completed in a couple of days without any follow-up being required."

"We needed a structural engineer to inspect the foundation of a home that we are purchasing and were recommended to contact Kemp. We are so glad that we did. Greg provided first class service. He was thorough and took the time to explain each step that he was taking, the purpose behind it, the potential results and what each could mean, and finally the actual results. He also took the time to educate us on some of the basic indicators of good and deficient or damaged home foundations. He was very personable and is great at making complex information simple enough for novices to understand. He also provided the inspection report almost immediately. We highly recommend Greg and his company’s services."

"Victor Bernard and their team took on a complex double bathroom renovation project in a 100 year old row home and did excellent work addressing the many unexpected challenges as we proceeded with demo, including rebuilding floor joists inappropriately damaged from a past renovation. While this of course made for a much longer project than planned, the quality of work was excellent and we love our new bathrooms."

Richard's Tree Service does both residential and commercial work. Since 1996, our tree company has continued to provide the community with quality work done by people who care about there clients. Richard and Rock Berube have more than 55 years of combined industry experience. Richard's Tree Service is family owned and operated business. Our office is professionally staffed. We have established ongoing relationships with our clients and have a substantial amount of repeat business. We are bonded and insured!

"Richards tree service came and did a $500 tree trimming job and I know have $1200 in damages to my backyard. On Nov 28th. 2020 “Richard Tree Service” came to my house to trim a tree in the backyard. They trimmed the tree with a fence and raised bed directly under the tree branches. Large branches were not cut in small chunks, but large heavy branches were cut and fell 20+ feet. While the branches were falling on the fence, a post in the center of the fence broke as well as the raised bed. The fence is now leaning because of the broken post. I reached out to Richards Tree Service many times from Nov 29th, through Dec 9th and they mostly avoided my calls at that time. After Dec 9th they reached out and said they will not do anything to mitigate this issue. The fence needs to be repaired. They say they will not repair anything. I got a quote for the repair and its over $1200 because there is a nice raise bed also attached to the post. They have since said that the post has mold and was compromised before they trimmed. All the other posts are not compromised and have no mold, and it is not easy to see the raised bed wood. I also don’t agree that the broken post is moldy, its broken. They want me to pay the $1200 to have someone repair the fence and bed. They also stated they wanted to be there when I have MY fence repair person come pay… I don’t have $1200 to dish out just for them to later say “still not paying”. They have insurance but refuse to use it. I have tried contacting the insurance information but their provider never responds. Also, even with all of this happening I tried to pay my bill. Apparently to pay they wanted me to take down someone’s wife’s phone number to give her my credit card. I get it that this is a small business person who may be just contracted through Richards tree service, but its still unprofessional. I do not feel comfortable giving someone’s wife my credit card and will be trying to pay a different way. I also had someone else come out to look at their job. They left cut branches just sticking out. I am not sure why they didn’t cut from the base of other branches or the trunk. I am pretty sure those random branches will just get decay and potentially hurt the tree. The job does not look good, but hey the leaves are gone I guess? I have limited options to proceed, I cannot pay the $1200 for the repairs and Richards Tree Service says they won’t do anything on their side. 1. They should have trimmed the branches in smaller chunks. Not large ones that would drop on the fence. Make sure you have a video of their job if you go with them, and tell them to make smaller cuts. 2. They should use their insurance, if the insurance finds that my backyard is all moldy (which I do not see) then they won’t have to pay for it, this is why you have insurance. 3. They should improve their billing solution. Its 2020 and there are safer ways to pay online with proof of receipts."

"It went well. The job was performed to the specifications laid out in the contract. It was finished on time with a professional work crew. My one quibble with them was how they dealt with our plants. They were less attentive to making sure the property was restored to its previous state. However, they fixed the issue promptly once it was raised. I would recommend GeoFreeze for foundation and engineering work."

Structural Engineering questions, answered by experts

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

Squeaky floors don’t always mean structural damage. Usually, it’s caused by friction somewhere inside your floor—whether it’s a loose floorboard or a gap between the subfloor and joists. If there is structural damage, you’ll notice other signs like soft or sagging floors, cracks that go from the wall to the ceiling, and horizontal cracks on your foundation.

A freestanding brick wall that's only one brick thick can usually stand six to eight feet high. If you need a higher wall, it should be at least two bricks thick for adequate stability, and it might require a footing to support the added weight. Additionally, some areas have regulations and codes dictating how high a brick wall can be, so check with local code enforcers to ensure your proposed wall complies with any regulations.
