We Have A Proven Window and Door Installation Process

Our proven process makes it super easy to work with us!

Step 1: Remove Old Units & Prepare Openings

The first step in a successful window and door installation is removing old units cleanly and preparing the openings. We ensure all debris, old caulking, or deteriorated materials are removed and assess the integrity of the surrounding frame.

We carefully inspect and prep each opening

We remove existing windows or doors with minimal disruption and clean the area to ensure proper fit and sealing of new units.

Here's the guidelines we follow:

Protect Yard & Surfaces
We cover plants, ground, and nearby areas to prevent damage from dust or debris.

Clean & Prep Openings
Old caulk and debris are removed for a clean, solid base.

Repair Frames
We fill, sand, and fix any damage or rot around frames.

Seal & Secure
Fresh caulk is applied, and any loose or unsalvageable parts are replaced.

Step 2: Repair Frames & Ensure Level

A secure, level frame is key for long-term performance. We repair any damaged wood, adjust framing where necessary, and confirm everything is square and plumb before installation.

This step prevents issues with drafts, leaks, or mechanical operation later on.

Step 3: Install & Seal Windows or Doors

We position and install each window or door according to manufacturer specs and seal all edges to prevent moisture or air infiltration. This includes flashing, insulation, and weatherproofing materials tailored to your home’s needs.

On-Site Installation Prep & Process

We carefully tape and cover nearby surfaces to prevent damage.

We move any furniture or items blocking the workspace.

Windows and doors are expertly fitted, leveled, and sealed.

We install trim, apply caulking, and attach hardware for a perfect finish.

Final Touches & Protection

Final Inspection & Adjustments
We double-check alignment, seals, and hardware for a secure fit.

Seal for Performance
Apply insulation foam and exterior-grade caulk to block drafts and moisture.

Protective Finish (If Applicable)
For stained wood doors or trim, we apply a clear coat for added durability and weather resistance.

Step 4: Interior & Exterior Trim Work

We reinstall or replace interior and exterior trim for a clean, polished look. Caulking and paint touch-ups are done as needed to complete the aesthetic and functional finish.

Step 5: Cleanup & Client Walkthrough

We tidy up the workspace, remove debris, and walk you through the final results. Our goal is to leave your home clean, functional, and better than we found it—ready to enjoy.

Finish Project

Carefully remove all protective coverings (tape, plastic, paper, drop cloths).

Sweep and vacuum the area to leave it spotless.

Complete any final touch-ups for a flawless finish.

Reinstall or return any items we moved, like downspouts, patio furniture, or grills.

Read what our happy clients say

From there everything continued smoothly. Oscar, the foreman, and his crew were very professional, clean and extremely skilled in all aspects of the job. The crew’s attention to detail was beyond outstanding. They were always on time and cleaned up completely at the end of each day. Their work ethic was so admirable. We are so proud of the way the outside of our home looks now.

First off when I was looking for a painter Dan was very quick to respond to my emails in a very professional manner. I contracted with Stellar Painting Services to paint our home based on the very positive Yelp reviews, and now I can add to the positive feedback. They painted the entire exterior of our home on schedule and for a competitive price. The initial salesperson, Marco, worked with us to accommodate our budget and he proposed a couple design elements with the painting that turned out very nice. He was punctual and flexible.

Oscar and his team are great to work with - professional, timely, great communication, you name it! They repainted over half my house, painted bathroom cabinets, fixed cracks in the ceiling, etc. Fair prices, honest and knowledgable. I won't hesitate to use them again.

I cannot stress how happy my wife and myself are with the quality of work that the crew did! Not only was the work perfect, but they also put all the appliances, TVs, stereo equipment back exactly as before they started.

Who you see on your consultation day is exactly who you get painting your home. We have an old home which required significant sanding down and touching up of old wood that had many layers of paint. They came in and spent over 2 weeks making it PERFECT. The attention to detail is incredible. We are now over 1 year from the the time the project was completed and it still looks perfect. He and his team are also incredibly kind and reasonable people. Look no further for your painting jobs!!!

Given that we have an older home, it needed extra attention and care in some areas. They really took the time to diligently prep the house and address any problem areas. I requested that the painting was done brush and roll, and it was done with great care. Simply put, they took the time to do it right from the start. They also promptly communicated throughout the duration of the project.
