"I hired TerraFirma Foundation Systems to level my home, expecting a professional job with clear communication, but the entire experience has been incredibly disappointing and costly. From the start, I hired the company to level the floors in my home, specifically to address a nearly 3-inch dip in my kitchen area, a 13x10 room. Yet after they “completed the job,” I still have a 1.5-inch dip in the center of the kitchen, and a corner of my home/kitchen that sits half an inch higher than it should be (above 0%), creating a full inch rise from the living room to the kitchen. Now they’re saying that leveling the kitchen wasn’t included in the original scope, blaming the remaining dip on my kitchen island and fridge being “too heavy” and lacking proper support—an issue they failed to identify in the initial assessment. To properly address this problem, they’re now asking for an additional $7,500, claiming this work was never part of the original job. This feels like a classic bait-and-switch tactic, and I can’t help but feel taken advantage of. To make matters worse, I discovered that they used an uncalibrated machine during the initial leveling when installing, which raised my house over an inch more than necessary, causing significant damage that wasn’t there before. Partway through the lift, they even asked me to sign a waiver to get my house closer to 0% level, effectively absolving them of any damage caused. The technician stopped mid-lift to show me the damage that was already occurring and warned that more would likely follow if we continued. I agreed to proceed, trusting their assurances and assuming their equipment was properly calibrated. I even pointed out to the technician at the time that it did not look level, and he assured me the machine was correct. Now, they refuse to take any responsibility for the resulting damage, dismissing it as “standard” and providing terms within the contract absolving them—despite them overcorrecting the home. There were also repeated measurement discrepancies, with reports showing one reading and verbal statements/emails suggesting different levels. When I sought clarification, I received vague responses and empty apologies. After all this, and nearly $30,000 invested, my floor remains unleveled. The only resolution TerraFirma Foundation Systems has offered is for me to pay additional money to level the kitchen and to wait for the overcorrected area to “settle naturally”—a process that, according to their technician, could take anywhere from two months to ten years. I hired TerraFirma Foundation Systems to fully level my home, not to leave me with an incomplete job, inconsistent results, and vague promises. If you’re considering foundation work, I strongly recommend looking elsewhere—this company has left me with extensive damage, unexpected costs, and a significant amount of frustration."

"Vasiliy is an amazingly talented craftsman with many talents and years of experience. Our nearly 100 year old deteriorating brick chimney was leaking water into the interior of the house and had to be repaired. Vasiliy came highly recommended to me by one of the best contractors in Portland, and I called upon him to fix it. The chimney was red brick, but Vasiliy suggested a lighter, golden color brick as it was more economical. Since our house is yellow, the golden color looked even better than red brick would have, and I saved money. The chimney is beautiful, and the repair/rebuild was so well done that Ithink it will last another 100 years,"

Patios questions, answered by experts
Alternative landscaping materials similar to pea gravel include wood chips, decomposed granite, crushed stone, and pebbles. You can also invest in specialty landscape rocks such as quartz, river rock, lava rock, and Mexican beach pebble. While many of these stones will cost more than pea gravel, some are more ideal for designing an attractive garden bed or managing drainage.
If it’s time to remove your deck, there are several advantages to replacing it with a patio. For example, you’ll pay much less to build a patio than a new deck, especially if the framework is compromised. A patio also needs less maintenance and will last longer. However, replacing your patio with a deck may not be an option if your terrain is on a slope.
It depends on whether you’re looking at residential or commercial buildings. For residential buildings, the 2018 International Residential Code asks for a maximum riser (or rise) height of 7 3/4 inches and a minimum tread depth (or run) of 10 inches.
For fixed stairs in commercial buildings, OSHA requires a rise between 6 and 7.5 inches, with a run between 10 and 14 inches. The standards are different for spiral staircases.
Labor and pouring adds between $8 and $18 per square foot to your total for concrete delivery. Especially for larger projects, it’s usually a good idea to hire a professional concrete delivery company when it comes to installing concrete surfaces even though it will undoubtedly cost more to hire a pro to do the work for you.
Crumbling concrete steps will affect your ability to drill into the material and affix a sturdy railing. If the damage is primarily cosmetic, you might be able to DIY the repair with a patch kit. If the concrete is badly crumbling, hire a professional who specializes in pouring concrete. The average concrete step repair cost is $500 from a professional, but the extent of the damage will determine your actual cost. The professional may recommend a replacement if the damage is extensive.
