"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

At HavenHub, your satisfaction and peace of mind are our top priorities, and we're honored to be a part of your home journey. Welcome to the HavenHub family, where your home is our passion.

"I truly regret hiring HavenHub for my backyard project. After a salesman came to our door, he designed our landscaping plan — retaining wall, stairs, shed pad, boulders, and sprinklers — and quoted $24,995. I paid in full around July 8, 2025, with a contract promising completion by July 28. No one ever showed up until I contacted them. Since then, I’ve dealt with four project managers, endless delays, broken promises, and almost zero communication. One crew came but didn’t know what they were supposed to do and couldn’t reach anyone for direction. Another poured a footing wrong, according to one of their own workers. Months later, my yard is still torn apart, and HavenHub continues to ignore me despite taking full payment. I’ve had to involve a lawyer just to try to get a response. Terrible communication, unreliable crews, and no accountability. Be very careful before hiring this company."

French Drains questions, answered by experts

Small clogs will eventually break down, but only if the clog is made up of toilet paper or waste and this can take time. If you don’t have another bathroom, it's best to fix a clogged toilet with what you have available. Solid objects flushed down the drain, however, require manual removal.

With a one-way cleanout, you can access your sewer line from one direction. Depending on the way it curves, a plumber can either access the side of the pipe that goes into your home or the side that goes to your yard. On the other hand, two-way cleanouts allow pros to access both sides of the sewer line, thanks to their dual-pipe design (they’re usually U-shaped).

Conventional drain cleaners, like you might buy at the grocery store, use bleach (sodium hydroxide) as the main ingredient. On the contrary, biodegradable drain cleaners use gentler ingredients such as baking soda, vinegar, and boiling water to clear out drains. 

Bleach is extremely corrosive and releases harmful gasses—hence the need for wearing safety protections like rubber gloves, eye goggles, face masks, and long sleeves and properly ventilating the room while using bleach. Biodegradable cleaners, however, don’t use bleach. Therefore they are safer to use, especially if you have a house full of children.

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.

There are several signs that can indicate your leach lines are broken, failing, or in need of repair, including puddles of water or a marshy consistency to the ground above or around the pipes, slow drainage or plumbing backups inside your home, and noticeable odors or gurgling sounds coming from your leach field. Keeping your septic system properly maintained, including having your septic tank pumped at regular intervals, can help ensure your leach lines stay in good working order for a long time.
