WHAT YOU CAN EXPECT DURING THE PROCESS

checkmark

A Consistent, Prompt Schedule

Our team will arrive punctually each morning, and will stay until the workday is complete. Weather permitting, we will be back every day until your project is finished - no sporadic scheduling or unpredictable stops and starts.

checkmark

Power Washing

A surface must be clean for successful paint adhesion to be possible. If there is visible dirt, mold, or mildew on your home, we begin with a thorough, professional pressure washing.

checkmark

Respect for Your Property

From ladder mitts to covering landscaping, we take every precaution to ensure that your property is protected. After all, it is not just a job site, but your home!

checkmark

Priming

Primer is essentially the foundation that your paint is built on, allowing for secure adhesion, coverage of any repairs or blemishes, and durability. We use only high-quality products that we know from experience will perform as they need to, maximizing the value and benefits for your home.

Daily Clean-Up

Our day is not considered complete until we have thoroughly cleaned and tidied the area where we worked, removing all equipment, coverings, tools, etc...

Thorough Surface Preparation

The difference between a disappointing paint job and one that endures (and looks beautiful) is found in surface preparation.These absolutely essential steps may include:

  • Sanding and Scraping
  • Dry rot repairs
  • Removing old, brittle caulk
  • Puttying
checkmark

Caulk and Putty

It may not be a glamorous component of the painting process, but it is vital. Caulk fills and seals any gaps, protecting your home from both pest and moisture intrusion, and leading to increased efficiency as a whole. 

Puttying is the process of filling any small holes in your siding, allowing a flawless, smooth finish.

Painting

On a case-by-case basis, we will carefully analyze and put together the very best plan of action for your specific property. This plan will include product choice, color consultations (if needed/desired), application techniques, and more.

Final Walk-through

Every step and stage of the process will be directly overseen by an on-site Crew Leader. When your project is complete, a Foreman will complete a walk-through with you, at your convenience, just to ensure that the work was completed to your standards (and ours).

A.G. Williams was asked to strip and re-varnish my double oak entry doors. The doors had a good amount of ornamental molding and detail work plus a half moon glass panel on each leaf. All of which, over 20 years, had turned grey with the finish peeling and opening up the wood to the weather. The doors were a mess. I had a difficult time finding someone who was willing to undertake the project. A.G. Williams reviewed the project, provided a fair price for the work to be done and a solid plan to do the work over 4-5 days. They provided excellent protection to avoid sanding dust getting in my home. The tech spent 3 full days sanding, with much of the sanding done by hand and when he was done the sanded doors looked better than new! The tech (Gideon) than proceeded to carefully brush on 3 coats of marine varnish over 3 days, pausing for weather & dryness of the preceding coat. When he was done the doors looked spectacular!! In addition to a top notch tech they also provided supervision to oversee the job and check in with me when the job was done. This was my first time using A.G. Williams and I couldn't have asked for a better company and job. When I enter my house through those doors it puts a big smile on my face.

Outstanding, professional, beautiful paint job by Pedro, Marco and Pablo! My new hardwood floors were covered with paper and drop clothes perfectly and the team was sincerely a pleasure to work with. My aging co-op apartment walls and ceiling needed a lot of prep work and the end result is stunning. I’m extremely happy and will use AG Williams for future paint jobs. Quality work is never cheap!
