"This is my second time working with Encore Builders and they killed it once again! These guys are the best. Iâ ve been doing lots of renovations in my house over the past year. Some of the projects have taken months of planning and work but Encore Builders is always in and out. My home is on a hillside and the backyard area needed some work. Oz and Brandon put together a 3D image and we chose out the style I wanted. I was amazed. Some simple stepping stones really elevated the space. Project took two days and we didnt even notice they were here. The crews were quick but didnâ t compromise the quality of the work. You can tell they are a hardworking company. Very impressed with their work yet again. Thanks Encore Builders team!"

"I heard about SES from my friend. He did last year a kitchen remodeling project with them. I wanted to renovate 2 bathrooms, so I called them right away and got 4 more quotes. I felt more comfortable with SES and decided to do the project with them. The result came out greater than I imagined. Thank you guys"

"John and his team did a great job on our backyard. John was very knowledgeable and had great suggestions and made sure we got what we wanted in the simple and clean look we were going for. We appreciated that they worked quickly and got the project done in about a week even during the heatwave we were experiencing at the time. He even came back to fix an issue with the turf that had been caused by the heat after the job was completed. It's so nice not seeing any more dirt and we are very happy to be able to fully enjoy our simple, low maintenance back yard."

"We had a stoppage in our patio drainage system near where several pipes meet. It wasn't clear exactly what the best avenue of attack would be. I suggested one opening which I thought was the straightest shot to the problem, but there was another the tech wanted to try first. That one seemed to lead to a T that couldn't be passed. The tech then used my original suggestion and that turned out to do the trick after some struggle with the blockage. There is usually an additional charge for going down more than one drain hole, but since success came with my original suggestion there was no additional charge which I thought was fair. In any event problem solved quickly and for the agreed upon price.
BTW, concerning the price, there is a rate sheet on their web page that lays it all out which I appreciate. There are 3 tiers: regular, overtime and double time which correspond to regular hours, off hours/weekends, and late hours/sunday/holidays. I had the work done on a Saturday morning so the indicated rate was overtime. However, there was a moment of confusion at the point of final payment when the office claimed it should be double time since it was Thanksgiving weekend. The rate sheet, original over the phone conversation and the quote from the tech on arrival all were for the overtime not the double time rate. To their credit, this was honored without too much fuss. The take away here is make sure you know which rate you are expected to pay especially when you are booking on or near a holiday. For example, is the Saturday of Easter weekend double time? It might be.
Anyway, great experience. I recommend The Drain Co.

"Mr. Parks and his workers were thorough, polite and efficient. My gutters were full and badly clogged because of several years of neglect. They removed all debris from my roof and dug out the gutters by hand until they got water freely flowing through the downspouts. It was a positive experience from beginning to end."

Excavating FAQs, answered by experts

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.

Dumpsters work best on hard, study, and level surfaces made of asphalt, stone, or concrete. If the surface is uneven or too soft, the dumpster could get stuck or tip over when filled. Keep in mind that you must obtain a dumpster permit to keep it on a city street in many areas.

The best type of soil to build on is a mixture of sand and clay, known as loam soil. Loam soil has the best combination of these soil types to build a foundation on. The clay particles help with water retention, so it won’t erode like sandy soil might, and the sandy particles help with drainage, so you won’t see unsafe soil expansion or have an increased risk of leaks from water sitting against your foundation.

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

There are several methods to hollow out a tree stump, and the best one depends on your tools, experience, and priorities. Common methods include using a chisel and hammer, a chainsaw, or burning.

  • Chisel and Hammer: This is often considered the easiest approach for those with limited tools or experience, though it is the most time-consuming.

  • Chainsaw: Using a chainsaw is the fastest method, but it comes with significant safety risks, especially for inexperienced users.

  • Burning: This can be an effective method, but it is not recommended unless you can first drill holes into the stump. Without holes, the stump will be difficult to light and may not burn completely through.

A power drill with at least a ⅜-inch diameter bit can make the job quicker and easier, regardless of the primary method. While you can use a chisel or chainsaw without a drill, it will require more time and effort. Always wear protective goggles and thick gloves, as splinters are an inevitable risk.
