Since 1990, Gordon W. Frazier Tree Service has been providing excellent tree care and service for residential and commercial customers throughout the Northern and Central Virginia areas. Our many services include but are not limited to all phases of tree care and removal, hazardous and dead tree removal, pruning, dead-wooding, trimming, crown reduction, tree maintenance and preservation, stump removal, bucket truck services and much more. As a family owned and operated company, we are committed to the personal care of your trees. Tree care is more than our job; it's something we are proud of. We're always happy to inform you about the work we're doing. We consider it important that you're aware of the benefits of each task we perform - not only for your security, but because we enjoy sharing our knowledge. If you ever have questions about what we do, just ask us! Call us today for your free estimate.

"Awesome end-to-end experience! After two other tree service arborists inspected trees with me but then failed to actually send estimates, I searched Angie's List and read many of Gordon's reviews. I left him a voicemail on a Friday. He called me Saturday and was willing to visit that weekend. Since I was busy over the weekend, he agreed to call Monday or Tuesday. He called Tuesday at approx. 11am, indicating he was in the area working a job and could be by in 30 minutes. I agreed to meet him. We inspected my four large shade trees (2 sycamore and 2 maples) and I explained we needed better visibility from front porch, unblock view of a corner stop sign, and ensure no growth into siding. He explained his additional recommendation for overall thinning and shaping. He provided an on the spot verbal estimate of $800 and when I asked if he accepted a credit card, he indicated yes, but would charge only $750 if I wrote a check. I had researched average job costs and Gordon's quote was very reasonable. I then asked what his lead time was and he indicated his crew was finishing a job nearby and they could be by in an hour after they ate lunch. He and his crew arrived promptly an hour later, a crew of six total, including Gordon. Gordon rang the doorbell and asked me to review first tree trimming with him before he moved on to remaining three to ensure it met my expectations per our earlier discussion. After finishing, Gordon asked me to walk our property and review pruning for all four trees. His crew was well organized, worked together like clockwork, and Gordon was right there with them working and directing to ensure all trees were pruned to expectations and clean-up was thorough. Our yard looks "larger" now and is very open with the thinning Gordon recommended, as they removed overlapping and dead branches to include providing more ground clearance. They look great and Gordon indicated they shouldn't require pruning again for at least five years. I'll now hire Gordon for annual tree / shrub maintenance (fertilize, insects, disease prevention) and fire the other provider that had provided that service but failed to provide a pruning estimate. I strongly recommend Gordon and his team for any tree related care! Well done!"

"Johnathan Castillo came out to discuss my vision for landscaping across the front of my house. We recently purchased it and the previous homeowners had completely removed all shrubs and replaced them with sod. We developed a plan on the spot. The scope of the job was about 100 feet across the house and 5-8 feet deep from the house to an existing brick walkway. The job was completed in one day, including removing the sod, installing over 150 plants, mulching and laying out pea gravel. I am very pleased with the results and look forward to seeing it all mature over the next 3-5 years."

Arborists questions, answered by experts

Rather than using a common two-by-four piece of wood for a rafter, you probably will use two-by-six, two-by-eight, two-by-ten, or even two-by-twelve boards. Wider lumber is typically a better choice in a larger building as it provides more sturdiness. Some installers may use wider lumber for rafters near the edges of the roof, where the greatest stress occurs, and save money with narrower lumber toward the middle.

On average, a prefabricated pergola kit takes one to four hours to build. Prefabricated pergolas are the fastest to install and could save you money, while custom pergolas can take several days to install, ranging from eight to 16 hours. The number of workers on the project can also impact how long it takes to install a pergola. 

If you need to build a concrete slab, level your property, or remove obstacles from your yard before building a pergola, then your project could take several weeks to complete.

Building a pergola yourself costs less than hiring someone to do it for two reasons. First, a contractor will charge a markup on the materials. Second, you’ll save the entire cost of labor. In exchange for the money you save, you’ll need to dedicate at least one full weekend to the project.

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.

There are a few differences between pergolas and gazebos. Both structures provide shade, but pergolas are more minimalistic, with four posts and a terraced roof. Gazebos usually have an elevated floor and are typically shaped like a polygon with six or eight open-air sides and two small sets of steps leading up to the platform. Gazebos also tend to have pointed, shingled roofs and ornate accents. If you want a structure that keeps out water on rainy days, a gazebo may be a better option—though you can purchase an awning to go over your pergola to keep out water.
