Five mistakes homeowners make on their first major remodel

The five most common mistakes El Paso homeowners make on their first major remodel. From contractors who have lived all five with clients. And what to do instead.

We have run hundreds of residential remodels in El Paso and Las Cruces over the years. The same five mistakes show up over and over on first-time projects. They are not mysterious. They are predictable. And every one of them is the kind of mistake that you do not feel until month two, when it is too late to undo.

Here they are, in order of how often they hurt the project.

Mistake 1: Picking the contractor on price alone

The lowest bid is almost always the most expensive job. We have watched this play out for two decades.

Three contractors come out, and the homeowner picks the one whose number is fifteen percent below the other two. Six weeks in, the change orders start. The lighting allowance was too low. The tile choice "wasn't included in the base scope." The bathroom subfloor was rotted "but that wasn't visible at quote time." By month four, the cheap bid has caught up to the other two numbers, but the relationship is poisoned and the schedule has slipped.

What to do instead: compare the scope descriptions, not the totals. Ask each contractor what is excluded. The contractor whose proposal is longest and most specific is almost always the best price for the actual work.

Mistake 2: Falling in love with a finish before the structure is set

This shows up most in kitchen and bath remodels. The homeowner sees a quartzite slab they love, picks it, and signs the contract. Then during demo, the floor slope is found to be off, the wall in the new design is load-bearing, and the layout has to change. The slab does not fit the new layout. The slab is now a $3,000 paperweight.

What to do instead: get the structural scope locked before any finish gets ordered. Counters, tile, cabinetry hardware, and lighting fixtures should be the last decisions, not the first.

Mistake 3: Not setting a contingency

Every project has surprises. Homes built before 1980 in El Paso routinely surface galvanized plumbing, knob-and-tube wiring, asbestos in vinyl floor mastic, or settled foundations once walls open. None of these are surprises to a contractor who has done this for twenty years. All of them are surprises to a homeowner who has not built a contingency into the budget.

What to do instead: plan for 15 to 20 percent above the contract price as a contingency. If you do not need it, you have it for the next project. If you do need it, the project does not stall.

Mistake 4: Trying to live in the house through the work

For some scopes, staying is fine. A bathroom remodel with a second bath available works. An exterior re-roof works.

For other scopes, staying turns a clean six-week project into a tense ten-week project. Kitchen remodels during the cabinet install and counter fabrication phase mean no functional kitchen for two to four weeks. Whole-home renovations mean dust everywhere, water turned off intermittently, and contractors needing access at 7 AM every morning. Living through it is doable, but it adds friction to every decision and slows the contractor down.

What to do instead: have an honest conversation with the contractor at the kickoff meeting about which phases require moving out. Budget for the temporary housing. The cost is real but small relative to the project. The peace is large.

Mistake 5: Refusing to make decisions on time

Every residential project has a decision schedule. The cabinets need to be ordered by Week 2. The tile selection needs to be locked by Week 4. The lighting plan needs to go to the electrician by Week 6.

When a homeowner delays a decision by a week, the entire downstream schedule slips by a week. If they delay by three weeks, the contractor's crew has been pulled to another project and now you are waiting for them to come back. The schedule slip is rarely the contractor's fault. It is almost always a chain of small homeowner delays.

What to do instead: take the decision schedule from the contractor at contract signing. Block calendar time for each decision week. Treat the deadlines like work deadlines, because they are.

What good contractors do about these

A good contractor will run a kickoff meeting that surfaces all five before the work starts. They will set the contingency, walk the decision schedule, recommend a temporary housing plan if the scope requires it, and protect the homeowner from picking finishes that will not fit the final layout.

If the contractor you are interviewing does not bring any of this up, you are probably looking at a contractor who has had these things go wrong on previous jobs and has not learned from them.

The residential side of our site has a form that sends a project directly to our team. The first conversation is free, and we will walk you through the kickoff agenda before you sign anything, with anyone.
