"Gabriel arrived right on time, and spent half an hour troubleshooting my landscape lighting problem. The repair needed some sod lifted, which I will have done by the gardener. Gabriel was very polite and conscientious in looking for other solutions that did not require this. I will definitely call them again if I for electrical needs."

"     Wes is the owner of the company and is hands-on at every juncture.  He and his crew were professional and responsive.  His initial bid was about 20% more than comparable, but we elected to go with his company as we were interested in a high-quality build.  I must say - I believe we got more than what we paid for.  The finished product is amazing.  The quality of Wes' work is unmatched.  He makes sure that everything is done right - down to all the structural and grading details that may not be evident from the surface. 
     It took three months for him to start our job, but he was up front and honest about this when he gave us the bid.  He states that he only takes one job on at a time and I can confirm that this is the case as his crew was at our house almost every day.  I say almost every day since our job had a number of delays by the heavy rains this winter.  Our yard used to mini-flood with each heavy rain making it difficult to do any construction in when wet.  The drainage now is amazing with no more lakes in our yard after the rain.  
     He worked with us on all the details of the design including grass and plant selection, stone selection (pavers, stone for the side of the island, and granite for the top of the island), and light selection.  The building inspector commented on how well the gas lines, water pipes, drainage, and electrical were done.  We have a new house and the project construction superintendent came over to see what we were doing and commented "wow, this guy does things the right way".  
     There were several curveballs that popped up throughout the job that Wes dealt with very professionally.  There were delays due to rain as mentioned, but also due to the granite fabricator making an error and the granite had to be completely re-cut and re-done (no additional cost to us of course) and the built-in BBQ had to then be tweaked to fit the re-cut granite.  Wes was sure to fix everything and his words were always "I want you to be completely happy with everything".  I certainly am.  I will be using his company again in the future for sure as we also have a side yard to do later this year.   
      I am not sure to convey how impressed I am with the quality of work and professionalism that Wes and his company deliver.  Don't dismiss the higher price of his bid.  You get what you pay for.  I have neighbors that used cut-rate contractors and they have had major headaches and are not happy with their experiences.  I am happy to tell Wes that I am completely happy with my experience.

"I added a new 375 square foot bedroom to my home thanks to Be Green Builders. I did not expect the work to go so smoothly but they really know what they are doing. I got new engineered wood floors, new paint and added a closet and recessed lights as well. I really expected everything to cost more but they gave me a great price and finished the job within the time frame they discussed with me originally. I saved a lot of money, time and the work was done to perfection. I have no complaints and all the workers were courteous and focused on my needs. I can’t thank them enough for the great job they did."

Exterior Lighting FAQs, answered by experts

Depending on complexity and materials, costs range from $150 to $500 per fixture.

Outdoor lighting repairs typically take between 1-3 hours. The exact duration can vary depending on factors such as the complexity of the problem, the extent of the damage, and the ease of access to the lighting fixtures and wiring.

While wet-rated and damp-rated lighting is designed to handle contact with moisture, there’s a difference between the two. Wet-rated lighting is safety-rated to be placed in areas with direct exposure to water, including your shower. Fixtures classed as wet-rated are made with waterproof seals to protect the filament and other electrical components from water and moisture. 

Damp-rated fixtures can be used in places with some moisture contact, but not direct exposure. They don’t have the same waterproof seals used in wet-rated fixtures. Damp-rated lighting can be used on your bathroom ceiling or along a wall outside of your shower.

Flickering lights, intermittent outages, or physical damage to fixtures signal immediate repair to avoid electrical hazards.

Table lamps, floor lamps, chandeliers, desk lamps, and antique or decorative light fixtures that hold sentimental or aesthetic value are commonly repaired.
