We are not a big company that you have to go through all the phone calls. Owner Andy Zhang will be the one to answer the phone, provide you the bid, and supervise and inspect the work before finish. We are so confident in our work, quality, and over all experience that we don't need any money down. Our customers don't pay us anything until the work is done and customer is happy! For a house on the market, in most cases, we allow owner pay the full bill through escrow at closing. We pride ourselves in treating every customer with honestly.We looking forward to hear and serve you soon!

"We hired them to take down two giant conifers in our front yard. They were really professional and amazing at their job. They fixed our fence after an unfortunate accident where part of the tree fell on it which was fine because they made that part of the fence better than the rest. Anthony and Kathryn kept in contact throughout the process and were amazing."

"At every step along the way they were thorough and professional. The estimator provided a very detailed scope and quote and patiently answered my questions. The installation crew was quick, efficient, friendly, and were so meticulous with their prep that up you couldn't even tell they were here after they left. I also appreciated the "after-photos" they sent me, it looks great!"

Basement Waterproofing questions, answered by experts

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.
