Can I wash my own roof?

• <div><p>It is possible to wash your own roof, but we don’t recommend it. First, getting up on any roof is dangerous without proper safety equipment, especially if wetting a metal roof and making the surface slick. Additionally, it’s easy to damage your roof or force water between roof seams if you <a href="https://www.angi.com/articles/can-roof-cleaning-extend-life-my-shingles.htm">use a power washer</a>, which can lead to property damage. Hiring a professional roof cleaner will save you time, keep you safe, and ensure that your roof looks new again without damaging it in the process. Plus, roof cleaning is a relatively affordable home improvement project.</p></div>

Q: Should I use bleach in a pressure washer?

• <div><p>Though bleach is a great way to kill mold and mildew around the house, you should never, under any circumstances, use bleach in a power washer. Bleach is a potent chemical that will destroy the pressure washer from the inside out. If you&rsquo;re worried about killing mold and mildew, you should instead hire a pro who will use a safe but effective cleaning agent when pressure washing your home.</p></div>

Q: How long does professional power washing take?

• <div><p>Generally 1-2 hours, depending on the area and level of dirt accumulation.</p></div>

Q: Can I powerwash my business myself?

• <div><p>While DIY power washing is possible, professional services ensure thorough cleaning, proper pressure levels, and avoidance of surface damage.</p></div>

Q: What is most important when buying a pressure washer?

• <div><p>One of the most important factors to consider when buying a pressure washer is not just psi but also the machine&rsquo;s overall cleaning power. This is based on both the psi and the GPM. Look for a cleaning rating, or effective cleaning unit (ECU), of up to 8,000 for most residential cleaning projects that require a pressure washer.</p></div>

The work was spread over a very long time. I had 2-3 months where I couldn't get anyone involved to return my calls and tell me what was going on. The original salesman was about the only one who would call back but he had little control over what was happening. When the gutter replacement was...

we had just bought our house and found the front load washer had a lot of mold and mildew on the door seal/bellows. I had called John's appliance and the owner Mike had to order the seal. After a couple of weeks he arrived with the seal and did a great job installing and cleaning up afterwards.
