RC&G is an acronym - it stands for "Richard, Charlene, and the Girls", because it's a great reminder of what I'm working for. I'm Richard and my wife and daughters are the most important thing in the world to me. Also hugely important to me is doing great work in my business as a handyman. I've always been mechanically inclined and good at fixing whatever's broken. With decades of experience, now I'm truly a master handyman. Whatever you need, I'm here to get it done. I respond quickly to contacts and give an accurate estimate. Then I arrive as scheduled, do the job right, and leave your house as clean as I found it. I'm looking forward to meeting you!

"Project went fine. Richard was very professional and accommodating!"

Long Distance Moving & Storage. Household, Commercial, International, Corporate services available. Our Mission is To exceed expectations on every move. We live this day in and day out. Our service is top notch and fully efficient. Our trucks are perfectly equipped for moving with Pads, dollies, Plastic and much more. We provide Long Distance Moves across the entire country, directly from our West Coast HUBS located in AZ, CA, OR and WA. Or, we team with our partner companies to complete moves together. We are proud to provide a service that no other company offers; Dedicated Trucks. This means that your belongings are loaded on the truck and not combined with anyone else’s items (from/to west coast only). They are not transferred to other trucks or facilities in route which causes damage and loss of items (typical with van lines). We have a set loading day and unloading day. This is by far the safest way to ship. Our interstate rates are per 24ft moving van that holds up to 8,500lbs or 1400CuFt. Some customers require one truck and some require more. One truck holds the average 1800SqFt.

"I cannot say enough great things about All Service Moving—and ESPECIALLY Rico and Reyes, who were absolute lifesavers for my last-minute move. After another moving company bailed on me the day before my scheduled move, All Service swooped in and saved the day. Rico and Reyes showed up EARLY, upbeat, and ready to tackle the challenge—even with super heavy furniture that usually requires a 4-person crew. Somehow, the two of them handled everything like pros without a single scratch or ding—on the furniture or either home. What really stood out was how personable, kind, and thoughtful they were. They moved quickly and efficiently, knowing I was paying by the hour, but never once sacrificed care or quality. They were kind to my mom (who was helping me out), and so sweet to my two dogs too. If you’re planning a move, ask for Rico and Reyes by name. They went above and beyond, and I want their team to know what a fantastic job they did. They deserve every bit of recognition. 100% recommend."

"Oscar truly stands out as a contractor who cares deeply about his clients, and that’s exactly how he made me feel. I reached out to five different contractors to assess my bathroom and offer ideas, but my experiences varied significantly. Some were overly sales-driven, others dismissed my ideas entirely, and one didn’t even follow up with an estimate. Oscar, however, was a breath of fresh air. He arrived on time, listened attentively to my ideas, and offered thoughtful suggestions. He was highly collaborative with the other workers on site, making sure everything was well coordinated. Oscar's expertise in the industry is evident, and he’s exceptionally creative when it comes to problem-solving. When he identified additional challenges during the project, he took the time to offer practical solutions, demonstrating his commitment to delivering the best result.

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

Boiler Repair questions, answered by experts

Repair costs typically range from $200 to $1,500, depending on the issue, such as leaks, burner malfunctions, or thermostat failures. Complex repairs involving heat exchanger replacement can be more expensive.

Once you know where your bleed valves are and how to use them, bleeding out heaters is a quick process. Expect it to take around 10 to 20 minutes, possibly longer if you have a lot of heaters or are still learning how they work. If you have a central bleed valve on your boiler, the process still takes the same amount of time. Make sure you have any keys necessary to turn the bleed valves on. Without bleed valves, the process should take around three hours.

The average house radiator has a life span of around 10 to 15 years. However, if you keep up with maintenance, such as bleeding the radiator once per year and removing any signs of rust as needed, your radiator may last 15 to 20 years. Consider hiring a pro to inspect your radiators annually to keep them in the best condition possible.

It is almost always more affordable to repair a radiator than it is to replace one. The average radiator repair cost is around $150, and it’s typically about ten times as expensive—around $1,500—to replace a radiator. A repair usually takes under an hour, too, while a replacement can take several hours, making it less of a time commitment to repair one.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
