"Very knowledgeable. Originally our new wall oven would not work due to some issues with the electrical. Brian Hamilton was able to converse with the oven installers and get the oven working. I highly recommend Hamilton Electric and would use them again. While on site Brian also replaced a wall switch that regulates the light, exhaust fan and heat. In the past people have had to cut through the outside hallway wall to have room to replace the switch. and than plaster the hallway wall. Brian replaced that switch in less than 15 minutes."

"We recently hired Geico Builders for a full home remodel, and the entire experience was fantastic. Their team worked quickly without cutting corners, and everyone who came into our home was friendly and respectful. They kept us updated throughout the project and made sure we felt comfortable with every step. What impressed me most was how clean they left the house each day no mess, no clutter. The final result turned out even better than we imagined. Truly a professional crew."

"What a wonderful experience working with Welcome Home Landscape and Lawn Care. A tree company had unexpectedly taken down a eucalyptus tree, destroying my back fence, leaving a glaring view of my neighbors and creating a crisis for me and my three dogs. Ken from Welcome Home walked the land with me and we brainstormed together. He was kind and understanding, had great ideas for what we could do, and together we developed a plan in several stages that I truly believe will make a big difference. He recommended a fencing company that came out right away. We put in a deer fence that is such an improvement. Then Ken came and cleared the debris from the land, leaving a forest floor of light mulch from the leaves. The land has never looked better. Our next stage is to plant. I so look forward to working more and seeing it all flourish. I feel truly blessed to have found this company and worked with Ken. And my dogs are happy too."

"No more than 5 minutes after I had submitted an inquiry to Horticultural Services, I was contacted by Chris. From the moment I spoke to him I could tell he was a professional. Him and his team showed up precisely on time, and took the utmost care in trimming large overhanging branches. The quality of work, timeliness, communication, and professionalism were impressive enough to encourage this review. They also are very fair with their cost and services.

Arborists questions, answered by experts

A pergola needs to be anchored, and typically, concrete is the best anchor option. Pergolas should be anchored to a concrete slab or concrete footings, and this is commonly required by municipal building codes. When applying for a permit to install a pergola, be sure to check the anchoring requirements as well.

Pergolas may have a 50% to 80% return on investment, whether they’re standard, manual, motorized, or smart pergolas. Your pergola will add more value when you choose a structure made from durable, long-lasting materials and when the pergola is properly installed by a professional. Extra features like a motorized roof, smart louvers, and heaters or misters may give you a better ROI.

You have several options you can choose from for climbing plants without damaging your siding. Climbing hydrangea and Carolina jessamine are two options, and jasmine, honeysuckle, and sweet pea are a few others. Look for these climbing plants to add lovely curb appeal and are less likely to cause damage to your siding.

Though this is a project that can be DIY-ed—there are kits available for $600 to $7,500—hiring a pergola pro will ensure the final product is structurally sound. A savvy homeowner may already have all the necessary tools and know-how to build a DIY pergola, but the difference in cost isn’t that much, and having help will make the process easier in general.

Turnbuckle weight loads vary depending on their size. Smaller 1/4-inch turnbuckles have a weight capacity of about 500 pounds. A 3/8-inch diameter turnbuckle, which is strong enough to handle most residential fence gates, can handle a working load of 1,200 pounds. Larger 1/2-inch diameter models have a limit of 4,000 pounds.
