5 Reasons why HK Construction is the Best San Diego Home Additions Contractor

1) Family Values

First of all Marc Gieselmann (the owner and founder of HK Construction San Diego) built his business in a way that makes his mother proud. In fact, his mom was his first office manager back in the very beginning. She helped him get it going then moved on to new adventures. He still still frequently spends quality time with his mother to this day.

Marc is also a family man as well. His kids grew up in Poway where he still resides. And he has a good relationship with them too. Long standing relationships are very important to Marc. He has good friends going back several decades. And he has many employees who’ve been working for him for 20+ years. All this shows Marc’s outstanding character as a person.

2) Honest Contractor

It’s a well know fact that there are too many shady characters among general contractors. And so that makes a good reputable contractor hard to find. I’ll bet you are looking forward to finding a local San Diego home additions contractor who has your best interests at heart; someone who has a strong desire to do their very best for you. Marc values the same feeling as well. That’s why he carefully screens and hires only the best employees and subcontractors for his client’s projects.

Marc makes sure, to the very best of his abilities, that his clients are always 100% satisfied with his home addition services. That’s why his clients are more than happy to refer him and his company to their friends and family.

Did you know the he does not do any traditional advertising for HK Construction? Yet his company is always booked and ever growing. Why is that? Because he believes that honesty is the best policy. Because he values long friendships and solid relationships. And since he loves family he treats all his customers as if he was working for his own mother. That is why most of his new business comes from referrals (word of mouth) from friends and customers. He also relies on his website being found naturally on the internet. This way he can show people what they can expect when working with him.

3) Your Home is Where the Heart Is

House Addition House Expansion Pros & Cons

House expansion, also known as home expansion, home additions, and room addition home remodeling, is a popular topic in San Diego CA. That’s because people who live in San Diego tend to have a great sense of classic values in home ownership.

Unlike smaller projects such as paint or landscaping, a house expansion project is a larger permanent change to the home. Therefore it’s important to carefully consider the pros vs. cons of this process, from all angles, before hiring your San Diego home additions contractor.

Home Addition Pros

PRO: You Get What You Want

Unlike buying an old home and remodeling with paint and fixtures, a house expansion is more encompassing. You, along with your house expansion contractor, are starting from scratch. That way you get what you want right from the beginning.

For example, you might have an older house that was built one way then changed over the years by other homeowners. So this way you get what you are willing to accept.

But in contrast, a home expansion gives you space that you can claim as your own unique creation. Expanding your home is like designing a whole new house without the problems, time, and expense of building a whole new house.

PRO: Cheaper than Buying New Home

Assuming you have a decent cost basis, home addition by expansion may be cheaper overall than buying a new home. Especially when you figure in moving costs, home expansion makes good sense.

Additionally, if you still love your current home but just need more space, then home addition is the way to go. Imagine leaving your lovely comfy home and moving to a new cold sterile house. Wouldn’t you rather “stay home” than move your home? For many people the emotional impact of moving outweighs the cost and process of expanding a home.

PRO: Easier than Moving

During a house expansion project expect some displacement of available space. It’s only a short term minor inconvenience of less space and some work crews doing their thing. This for most people is so much easier than the moving process; which includes but is not limited to the following:

  • Holding yard sales and parting with belongings
  • Sorting, boxing, and packing
  • Not knowing where your items are when you need them
  • Driving, flying, moving to new home
  • Remodel new home to suit taste and/or function
  • Unpacking, setting up entertainment center, beds, furniture, etc.
  • Opening new utilities accounts, meeting techs to set up or install of services
  • Making new friends with neighbors
  • Kids starting in new schools
  • Starting new jobs, meeting new people

As you can see, sometime moving is a hassle that upsets the lifestyles and long term friendships of everyone in the household. So therefore staying put and remodeling your existing home is by far an easier choice.

PRO: Great High Cost-Value Ratio

House expansion usually pays for itself in the long run. Since adding more floor space (square footage) increases your home’s market value, then given enough time for real estate prices to rise then selling at a market peak, you could reclaim all your money and maybe even make a tidy profit as well.


CON: No Guarantee of Higher Resale Price

While some home expansion projects will increase your home’s value, others may not do quite as well on your local market. For example, a home theater room, or a swimming pool, or a massive workshop might be great for you, but not so great for other random home buyers. So definitely get what you want and enjoy it; just be aware that perhaps not everyone will want the same thing too. You should always consult with a San Diego home additions and home remodeling expert, such as HK Construction, prior to starting big projects to make sure if they’ll add monetary value. Call for details and then book a free in person home addition consultation.

CON: House Expansion Uses Property Space

Unless you are adding a second story, you will lose yard space by expanding your home. So if you have young children or pets that play outside, then they’ll have less space to enjoy outdoors. However, by making the yard smaller, you might recover time and resources due to maintaining less landscaping.

CON: Cost of Funding

Unless you can refinance your home, or have cash ready, then interest on a home expansion loan will probably cost more than a mortgage loan. What that overall cost is depends on your interest rate, time, and amount of loan. Do the math and see if the cost pans out for you. If you want a home addition for enhancing your family’s enjoyment of your current home, then this is a good fit for you. Since the cost of financing a San Diego home addition expansion via home loans is very affordable with current interest rates as low as they are (at time of writing). Basically, you can focus on what would please your family the most. However keep in mind that when you eventually sell that home, certain expansions and improvement can either increase or detract from a future resale.
