Exterior & Interior Home Improvement Contractor Maryland

Alvarado General Contractors, Inc.
Carpentry & Painting Montgomery Co, MD.

Alvarado General Contractors, Inc. are called to do repairs to many homes before the exterior is painted. These repairs can range from just a few fascia boards or brick moldings to windows, window sills, siding, corner boards, etc. In most cases the customer prefers to work with one contractor for both painting and repairs. This facilitates scheduling for our customers and allows us to make sure that the property is managed properly for the entire project.

We know that our customers have different needs so we try to estimate the entire project when doing residential painting or commercial painting projects to try and inform the customer of the total extent of the repairs needed prior to starting the painting project. This eliminates a lot of questions and frustrations the customer may have regarding the overall cost of the project. Repairing rotten wood is essential to completing the project properly, if rotten wood is painted over, the paint will eventually fail due to the moisture in the wood. We provide a detailed, itemized estimate so our customers are aware of all the rotten wood that needs to be repaired or replaced. Some contractors will state they will “replace rotten wood as needed” and at the end of the project you have a large bill for all the wood that needed replacing or repair.

Sometimes it is not possible to see all rotten wood when doing an estimate, but we notify the customer of any additional wood that needs repair that wasn’t noted in the original estimate before we begin any work.

We prefer to use materials that will not rot to replace your old rotten wood because they generally carry a 25 year lifetime warranty, depending on the product and will provide a better quality of surface for your painting project.

When you contact Alvarado General Contractors we will schedule all carpentry repairs first. We will then begin prepping the exterior for the new paint.

  • removing downspouts
  • protecting all non-painted surfaces with drop cloths
  • cracks and loose joints are caulked
  • recessed nail heads are puttied to lock out moisture
  • metal lentils and rusted areas are primed with a rust-inhibitors   
  • new wood, peeling and loose paint is scraped and then spot primed with an exterior acrylic or oil primer to protect bare wood and assist in the adhesion of new paint

We use Sherwin Willman, Benjamin Moore or Duron paints. These are high quality paints with 10-year guarantees. We recommend a satin or semi-gloss finish on the siding and a semi-gloss/gloss finish for the trim. These finishes provide better protection; fade resistance, chalk resistance and wash-ability in lieu of a flat finish to insure a professional exterior painting job.

We use both spray and hand brush application. There are advantages and disadvantages of both applications, which we can discuss with you at the time of the estimate. If you prefer a specific method of application, please let us know so that we can provide the proper pricing to insure a professional exterior house painting job.

Before we begin an interior painting project we:

  • Move or relocates furniture, furniture is then covered with plastic and floors are covered with drop cloths to insure protection of your property.
  • Drywall repairs are completed, including nail pops, stress cracks, drywall tape, etc. Cracks in the trim are caulked and a stain-killing acrylic or oil-based primer is applied as needed.
  • We use only the best quality paints in flat, matte, eggshell, satin, semi-gloss and gloss finishes. We recommend an eggshell, satin or semi-gloss finish on interior paint jobs where wash-ability is a priority.
  • When finished, we clean and dust the area painted, furniture is returned to its original positions and leftover paint is left for future touch ups and color matches.
