Merced Window Cleaning has served homeowners in Merced, CA, since March 2022, and concrete cleaning is one of our most requested services because clean concrete changes how a property looks from the street, removes slippery buildup before it becomes a hazard, and slows the deterioration of concrete surfaces that happens quietly over time. In the Central Valley, agricultural dust settles into porous concrete from spring through fall, and winter fog turns that accumulation into mildew, algae, and moss that a garden hose will not reach. We serve Merced and the surrounding area within roughly 35 to 40 miles, and we treat concrete cleaning as preventative maintenance, not just a cosmetic fix.
Every concrete cleaning job starts at a minimum of $250 and ranges to $450. From there, pricing runs $0.11 per sq. ft. when the concrete is not very dirty, and can go up to $0.33 per sq. ft. when the concrete is severely stained and the labor reflects it.
Final cost depends on:
Time-wise, smaller or lighter jobs may take around 1.5 hours, while larger concrete-cleaning jobs may take up to 4 hours. Oil stain removal is a separate add-on; pricing details are available upon request, and the chemicals may need to be ordered in advance, so it must be requested at scheduling. Estimates are free and most jobs can be quoted accurately over the phone.
If we are already at your property for a house wash, gutter cleaning or roof cleaning, adding concrete cleaning to the same visit comes with a bundle discount because the equipment is already on site. If a bundle applies to your job, we will note it during the estimate.
We apply a pretreatment first, then connect a surface cleaner to the pressure washer and work the entire area evenly. After that pass, a wand removes dirty water and loosened debris from the surface. We actively manage runoff so the finished area is genuinely clean, not just rinsed. The combination of year-round agricultural dust and winter moisture is what causes concrete in this area to deteriorate faster than most homeowners expect, which is why routine cleaning produces lasting results.
Patio concrete gets the same pretreatment, surface-cleaner pass, and wand rinse as driveway work. Clearing furniture and potted plants before we arrive gives us full access to the surface. If anything is too heavy to move on your own, we handle it when we get there.
Oil stain removal is requested and priced separately. Pricing details are available upon request, and we apply a degreasing agent with a pump sprayer, work it into the stain with a mop, absorb the mixture into a bucket, and repeat two to four cycles depending on severity, followed by soft washing, pressure washing, and a final rinse. For heavily soiled surfaces the rate may reach up to $0.33 per sq. ft. We will tell you honestly what results to expect before work begins.
We pick up the phone, follow up quickly, and get back to customers as fast as we can whenever something comes up. For homeowners comparing providers who all claim similar technical capabilities, reliable communication before, during, and after the job is often the most meaningful difference in the actual experience of working with a company.
We carry full licensing and insurance coverage up to $1 million on every job. That coverage removes personal liability from the picture for any homeowner who brings us onto their property, and it reflects the professionalism that separates a licensed local business from an operator working without it.
We have over 300 five-star Google reviews from homeowners throughout our service area, and we are happy to provide personal references on request so you can hear directly from past customers before making a decision. For first-time customers deciding between providers, both of those options offer a clearer picture of the real experience than anything we could say about ourselves.
When a surface has significant cracking, chipping, or permanent staining that limits what cleaning can realistically deliver, we say so at the estimate stage before any agreement is made. We would rather give you an honest assessment and lose the job than take payment on work that was never going to meet your expectations.
We run a 4,000 PSI pressure washer at 4 GPM, paired with professional surface cleaners, j-rods, an injector, and wand rinsing methods. The value is not just having capable equipment but knowing which attachment and technique fits the specific concrete condition and the type of treatment being performed.
Electrical devices and outlets near the work zone are taped and bagged when chemicals are involved, plants and landscaping are watered before treatment begins, and surrounding areas are rinsed thoroughly after cleaning is complete. We ask that pets stay inside during the service, and these precautions are built into our process on every job rather than something you need to request separately.
We take before-and-after photos on every job as a standard part of documenting the work, which is especially useful for homeowners who need records for themselves, insurance, or HOA purposes. Those photos are yours to keep, and electronic invoices with a full service description are sent after every completed job.
We founded Merced Window Cleaning in March 2022 with a long-term commitment to this area, not as a seasonal operation. We volunteer with Catholic Charities of Merced, and in 2023 we received the Angi Super Service Award. Being part of this community means our reputation is tied directly to every job we take on and every customer we serve.
We are deliberate about who joins our team because the people doing this work are on your property every day, and trustworthiness is a baseline requirement, not a selling point. We also invest in ongoing education and process improvement so that our work stays consistent and competitive without cutting corners on quality.
Call (209) 658-7454 or submit a quote request through our website and we will get back to you as soon as possible, typically within a day. Many concrete cleaning estimates can be handled right over the phone depending on the size and general condition of the area, so you may have a number in hand without anyone needing to visit first. Once you agree to the estimate, we schedule an appointment at a time that works for you. Automated reminders go out two days before and again the day before your appointment, and you will receive a call or text when we are on our way.
Before any equipment is unloaded, we look carefully at the full concrete area. We assess the level of dirt, grime, organic buildup, and staining across the surface, and we identify any cracks, chipping, holes, or structural damage that may affect what cleaning can realistically accomplish. If you want oil stain removal included, this is when that conversation happens, since it carries separate pricing and may require materials to be ordered before the appointment. Most jobs run between roughly 1.5 hours for smaller or lighter surfaces and up to 4 hours for larger or more heavily soiled areas, and we give you a realistic time range based on what we find.
We ask that you clear the concrete surface as much as possible before we arrive. Patio furniture, potted plants, smaller decor, and any items sitting on or immediately around the area should be moved when you are able, since full access to the concrete means a more thorough result and protects your belongings from overspray. If anything is too heavy or awkward to move alone, tell us when we get there and we will take care of it. On our side, we tape and bag electrical devices near the work zone when chemicals are involved, water your plants before treatment starts, and rinse the surrounding areas once cleaning wraps up. Pets should be kept inside during the service as a standard safety measure.
For standard concrete cleaning, we apply pretreatment to the surface first, then connect the surface cleaner to the pressure washer and move through the area evenly. Once that pass is done, we use a wand to pull dirty water and residue off the cleaned concrete, and we pay attention to where runoff travels throughout the job so the finished surface looks genuinely clean before we pack up.
For oil stain removal jobs, the sequence is different. We apply a degreasing chemical with a pump sprayer, work it into the stained area with a mop, absorb the mixture into a bucket, and repeat that cycle two to four times depending on severity. After those treatment cycles finish, we apply our soft wash solution, pressure wash the surface, and close with a final rinse.
Throughout any job involving water and cleaning solution, we actively manage dirty water flow from start to finish. We do not operate a wastewater reclamation system, but the City of Merced has identified pressure-washing runoff as a stormwater concern, noting that pollutants entering storm drains discharge untreated into local waterways, and we take that seriously on every job.
Once the surface is clean, we push any remaining dirty water and displaced residue away from the finished area so it looks right when we leave. Before-and-after photos are documented as standard, and we can share those directly with you if you want them for your records. Electronic invoices and receipts with a service description are available for every job, and payment is accepted by cash, check, card with a 3% fee, or Venmo. The day after service is complete, we call to check in and confirm everything came out the way you expected, and if something did not land quite right, we aim to return within a week to address it.
Every concrete cleaning job we do is backed by a 100% satisfaction guarantee. If the result was not what you expected, call us and we will return to address the issue. That process starts with the day-after check-in call we make to every customer, which gives both sides a chance to talk through any concerns while they are still fresh. When a touch-up or additional attention is needed, we aim to be back within a week.
The guarantee covers our service quality, our communication, and our commitment to returning and making things right when something legitimately falls short of what we described. What it does not extend to is promising a result that the condition of the concrete made impossible before we even arrived. When a surface has significant structural damage, deep cracking, chipping, or staining that has permanently altered the material, we say so at the estimate stage before any agreement is made, because that honesty is part of the guarantee itself.
We take specific steps to protect the area around every job. Electrical devices and outlets near the work zone are taped and bagged when chemicals are involved, plants and landscaping are watered before treatment starts, and we rinse surrounding surfaces after cleaning is complete. Pets should be inside during the service to keep them out of the work area. As for the concrete itself, if existing cracks, chips, or structural damage may limit what we can accomplish, we will tell you that before we start so expectations are accurate from the beginning.
Yes. A detergent pretreatment is part of our standard concrete cleaning process. In situations involving oil stain removal, we also use a degreaser and soft wash solution suited to the surface. We do not share specific chemical formulas or mixing ratios, but every product we use is matched to the condition of the concrete and the type of treatment being performed.
Yes, on request. Oil stain removal is priced separately from standard concrete cleaning and must be scheduled in advance, since the treatment chemicals may need to be ordered depending on the scope of the job. The process typically involves multiple treatment cycles before we finish with pressure washing and a final rinse. Pricing details are available upon request when you describe the staining during your estimate call.
We give every customer an honest assessment of what the surface condition allows before any work begins. If significant cracking, chipping, structural damage, or permanent staining is present, we explain what results are realistically achievable rather than letting expectations run ahead of what cleaning can deliver. Some customers decide to move forward with that understanding, and others prefer to wait. We would rather have that conversation upfront than collect payment on a job that leaves you frustrated.
The minimum for any concrete cleaning job is $250 and ranges to $450. From there, pricing runs $0.11 per sq. ft. when the concrete is not very dirty, and can go up to $0.33 per sq. ft. when the concrete is very, very bad and the work required reflects it. Oil stain removal is a separate service, and pricing details are available upon request when you provide details during the estimate conversation.
Smaller or lighter jobs may take around 1.5 hours from setup through cleanup. Larger concrete-cleaning jobs, or surfaces with heavy accumulation and significant staining, may take up to 4 hours depending on the total area and the condition of the surface.
Clear the work area as much as you can before we show up. Patio furniture, plants, and any items sitting on or directly around the concrete surface should be moved off when possible to give us full access. If anything is too large or heavy to move on your own, let us know when we arrive and we will take care of it before we get started.
We use a professional rolling surface cleaner, which is the spinning disc attachment that many homeowners describe as a rolling machine or circular scrubber. It connects to the pressure washer and produces a more consistent, even clean across flat concrete than a single wand pass. We also run a 4,000 PSI pressure washer, j-rods, an injector, and wand rinsing methods to move dirty water fully off the surface before we leave.
Yes. Before-and-after photos are part of our standard documentation on every job and are particularly useful for homeowners who want records for themselves, insurance, or HOA purposes. Let us know if you would like them shared directly and we will make sure you receive them after the service is complete.
Yes. We send electronic invoices and receipts with a description of the work performed after every job. As long as we have your email address on file, that documentation goes out to you so your payment record and service history are easy to keep and reference.
We accept cash, check, card with a 3% fee, and Venmo. If you prefer to avoid the card processing fee, paying by check is always a straightforward option.
Yes. We use the customer’s on-site water for all pressure washing work. You do not need to set up a separate water source or make any special arrangements before we arrive.
The agricultural environment of the Central Valley keeps dust consistently airborne for most of the year, and that dust settles directly into porous concrete surfaces. When winter fog and rain arrive, the accumulated layer creates the right conditions for mildew and organic growth to take hold. Concrete in and around Merced tends to become noticeably dirty faster than homeowners in other regions expect, and that cycle is why periodic professional cleaning works as a preventative investment rather than just a cosmetic reset.
Once surface cleaning is complete, we use a wand to actively push dirty water and loosened residue off the concrete rather than letting it settle back into the area. We do not run a wastewater reclamation system, but we manage runoff direction carefully on every job. The City of Merced has identified pressure-washing runoff as a stormwater concern, and local guidance notes that pollutants reaching storm drains discharge untreated into nearby waterways. Our team takes that seriously and controls water flow accordingly from start to finish.
