Even though I messed up the date they came, they were able to fit me in the next day. The men who did the work were responsible and respected my space. They wore masks the entire time and were quick, efficient and showed me any imperfections they encountered. They answered all my questions. I am very happy being able to look out my windows and see the mountain clearly again. Great job, I will be scheduling them to clean my windows again in 6 months

Two very capable and thorough cleaners did a very excellent job cleaning our house up and down. Spent all day making the house and windows shine. Roof was cleaned and treated, all windows and skylights were beautifully cleaned, siding washed down. They did a great job and we will definitely have them come again.

The entire experience from start to finish was seamless and professional. I started the process to have my Christmas lights installed with an online quote request. There was virtually no wait before my estimate was complete (within 24 hours), the agreement was completed online, and my service was scheduled within 3 days. I was pleasantly surprised when the dispatcher was able to bump me up by 9 days due to a cancellation. They met every timeline and expectation. My lights look fantastic, and my technician, Ryan was helpful and informative every step of the way. He walked me through exactly how my design would look and was prompt and professional. I look forward to continuing my relationship with this local business!

Exterior Cleaning FAQs

Most people take pride in their homes, and want to keep them looking clean and presentable. One way to achieve this is by pressure washing the exterior of the house. Pressure washing can remove dirt, grime, and even mildew from a variety of surfaces, including siding, stucco, brick, and concrete. In addition, pressure washing can help to extend the life of these materials by removing damaging pollutants. However, pressure washing is not a simple task, and requires a certain level of knowledge and skill. For best results, it is advisable to hire a professional who has experience pressure washing homes. While this may cost more than doing it yourself, it will likely result in a better overall outcome. In short, pressure washing your home’s exterior is definitely worth the investment.

The roof is one of the most important parts of a building, and it needs to be properly maintained in order to protect the structure from the elements. One of the most important maintenance tasks is to keep the roof clean. Over time, dirt, debris, and moss can build up on the surface of the roof, causing problems like leaks, blocked gutters, and even collapse. In addition, a dirty roof can cause your energy bills to rise as heat escapes from your home. A professional roof washing company will have the equipment and expertise to safely remove all of the build-up from your roof, leaving it looking like new. In addition, they can also treat your roof with products that will help to prevent future build-up. Schedule a roof cleaning at least once a year to protect your home and save money in the long run.

*Taylor at LBL Soft Wash was kind enough to give us some pressure washing advise.

There are a few things you can do to make sure you’re hiring a reliable pressure washing company. First, check to see if the company is licensed and insured. This will protect you in case of any accidents during the pressure washing process. Second, ask for references from past clients. A reputable company should be able to provide you with a list of satisfied customers. Finally, be sure to get a written estimate before work begins. This will help avoid any unexpected charges later on. By following these simple tips, you can rest assured that you’re hiring a reliable and professional pressure washing company.

Many homeowners never give their gutters a second thought – until they start leaking, become clogged, or start to pull away from the house. Unfortunately, by that point, it’s often too late to avoid costly repairs. That’s why it’s so important to regularly clean your gutters. By removing leaves, twigs, and other debris, you can prevent clogs and ensure that water can flow freely through the gutters. In addition, gutter cleaning helps to reduce the risk of water damage to your home by preventing rainwater from spilling over the sides of the gutters. As anyone who has ever dealt with water damage knows, even a small leak can quickly cause major problems. So don’t wait until your gutters are in disrepair – make gutter cleaning a part of your regular home maintenance routine.

Yes, you should definitely have your roof professionally cleaned. Professional roof cleaning services are essential to maintaining the health and integrity of a home’s roof. Keeping it free from dirt, debris, moss, algae and other organic materials is important to protect against roof damage that can happen due to water seeping into cracks in the shingles or through clogged drainage systems.

Professional cleaning companies use special techniques tailored specifically for the type of material used on your roof as well as its pitch and shape in order to get it clean without causing any damage. They also come with specialized equipment such as ladders or scaffolding so that they can access every part of your roofs surface easily and safely, allowing them to remove all kinds dirt and grime without missing any patches. This also helps avoid costly repairs down the road due to inadequate cleaning.

Professional cleaners provide an effective way of getting rid of unwanted materials from your rooftop while ensuring minimal risk involved regarding potential structural damages. Additionally their experience will help identify existing problems quickly so proper repairs can be initiated correctly at an early stage thus saving homeowner’s costly repair expenses down the road!

Special thanks to our friends at A+ Pressure Washing for this information!

It is recommended that you have your gutters professionally cleaned at least twice a year. In most cases, this would mean once in the spring and again in the fall. This will help prevent clogging and ensure proper drainage of your gutters.

It’s important to remember that having your gutters regularly cleaned is not just about avoiding clogs – it’s also about preventing water damage from standing puddles or overflow around your home’s exterior walls or foundation. Having properly installed gutter extenders can help catch any runoff before it has a chance to soak into those sensitive areas. Another great thing about professional cleanings is that they give professionals an opportunity to inspect all parts of your system – detecting potential problems early while they’re still fixable can save loads of money when compared with reactive repairs (i.e., reacting after something major has already gone wrong).

Soft washing is a process in which low-pressure equipment such as pump-up sprayers and garden hoses are used to apply cleaning solutions over exterior surfaces. Unlike pressure washing, soft washing sprays the cleaning solution onto the surface instead of using high-pressure, which can damage siding, shingles, masonry and other fragile surfaces. It works by lifting dirt and debris away from the surface without blasting it off. Pressure washing can disperse dirt particles while soft washing encapsulates them so they’re not redistributed throughout your property or into nearby waterways.

Soft wash cleaners typically contain biodegradable surfactants that break down organic matter like algae, fungus and bacteria without affecting plants or human health with dangerous chemicals. Soft washers also pre-treat affected areas with an algaecide before rinsing the entire area leaving behind a clean sanitized resting place for new microbial life to return naturally over time if necessary. The solution stays on longer than it would from pressure washing allowing more of the active ingredients to do their jobs better than short bursts of water can achieve with high pressure nozzles doing most of work.

Yes, roof pressure washing is safe if using the necessary precautions. Pressure washing can help improve the appearance of your roof while prolonging its lifespan. However, it is also important to be aware of the potential damage that could be caused by the pressure washing process itself.

Pressure washers are powerful machines with water streams ranging from 1000-4500 psi (pounds per square inch). If used incorrectly – such as focusing the nozzle too close to certain surfaces or pointing it upwards instead of downwards – this powerful stream may cause damage to shingles and other components on your roof, leading to costly repairs or replacement. Furthermore, if you are not experienced in power washing roofs, then you may risk damaging both yourself and your property.
